The landscape Change Program is an archive of paired historic and recent photos of Vermont landscapes. The program is funded by the National Science Foundation to digitally document how the Vermont landscape has changed over time.

The landscape of Vermont has changed considerably since it first emerged from the ocean during the collision of huge tectonic plates. For a time, geologically speaking, sediments that became Vermont had been in a warm tropical sea at the equator. Slowly they had moved north. Mountains were born and began to erode. Massive glaciers more than a kilometer thick blanketed Vermont. Soon after the glaciers left, Native Americans inhabited the area. Colonial settlers moved in, clearing the land and leaving just a quarter of the total area forested, making way for agriculture, then sheep, then dairy. Hundreds of hill farms sprang up and many were later abandoned as western soils called. Now the Vermont landscape is mostly forested and yet increasingly developed. The face of Vermont has changed dramatically over time. The shared appreciation and acknowledgement of this rich landscape history is the goal of this project.

[Summary provided by the University of Vermont.]

This compilation includes sites from existing county-wide landslide inventories, Vermont Geological Survey surficial geologic maps and publications, and sites from Vermont Agency of Natural Resources Stream Geomorphic Assessment. This dataset is a compilation of available data for active, inactive and relict (historic) sites and is not a complete inventory of Vermont landslides. The inventory includes historic documented sites and landslides verified by field visits or remote sensing. Points represent feature locations and are not indicative of feature extent. Definitions:Landslide: A feature formed by the downslope movement of rock and soil under the effects of gravity. The term includes a wide variety of falls, slides, and flows. They are identified by the presence of steep slopes and/or evidence of soil movement and surface erosion. Most are adjacent to streams. Features below 4 meters in height are not mapped. The mass failures identified during stream geomorphic assessment studiesare landslides.Gully: A steep, narrow stream channel incised into surficial deposits. The stream is commonly a first-order stream and the flow in the bottom is usually intermittent. Unstable gullies have very steep sides and commonly show signs of fresh erosion in the bed and/or at the gully heads.Gully head: The upstream tip of a gully. One gully may have several gully heads.Landslide-gully complex. A gully with substantial landslides on the sides or at the head.

These data are from collecting events beginning in ~1960s through early ~2000s by Ross and Joyce Bell and associates, as well as reliable records from literature gathered by the authors. Most locations of specimens were georeferenced by the authors on paper maps for each species using township borders as a reference when placing a location. Points from each of these species maps were digitized in a GIS.

Historic Properties (Points, Lines). These include State Antiquities Landmarks (SAL), National Historic Landmarks (NHL), National Register of Historic Places Listed and National Register of Historic Places Eligible (NRHP) properties, Recorded Texas Historic Landmarks (RTHL), Texas Centennial Markers, and Contributing properties as well as locally designated resources if available. These features are compiled from various TxDOT and consultant surveys & reports. These determinations are made by the National Park Service or the State Historic Preservation Officer (SHPO). Historic Districts (Polygons). These include State Antiquities Landmarks (SAL), National Historic Landmarks (NHL), National Register of Historic Places Listed and National Register of Historic Places Eligible (NRHP) properties. Whenever possible, contributing properties and locally designated historic features have also been included. All of these features and their designations are gathered and determined by the National Park Service, the Texas Historical Commission, or through various surveys and reports performed by TxDOT and their consultants. Historic Bridges (Points). These are bridges listed or eligible to be listed on the National Register of Historic Places (NRHP). A bridge that is rare in type, unusual from an engineering perspective, or historically significant because of its location or association with an important event or person may be deemed a historic bridge. This determination is made by the TxDOT Environmental Affairs Division (ENV) in consultation with the State Historic Preservation Officer (SHPO). Texas has numerous examples of historic bridges, including metal truss bridges, concrete arch or span bridges, and suspension bridges. Historic Resource Survey Reports (Polygons). HRSRs are mapped for each project's Area of Potential Effect (APE). The APEs are determined by industry standards and/or survey requirements. These map elements are updated approximately once a month to reflect any changes. Bypassed Relocated Bridges (Points). Bridges that have been bypassed or relocated for one reason or another. Many now serve only as pedestrian crossings or exhibits at various local museums. Some bridges were relocated by TxDOT, some by county entities, and still others were handled privately. TxDOT project information is included if available.Update Frequency: Monthly Source: TxDOT Environmental Affairs Division Historic Properties DatabasesSecurity Level: Public

(Link to Metadata) This dataset is a five category, nine sub-category classification of the bedrock units appearing on the Centennial Geologic Map of Vermont. The Centennial Map, published in 1961 (RF 1/250,000) by the Vermont Geological Survey, maps 136 unique lithological types across the state. The current dataset simplifies the 1961 map by defining five broad classes and nine subclasses of rocks of varying geochemistry and mineralogy. The classification was developed by a small team of geologists and ecologists in the autumn of 1998.

Historic Districts listed in the State Register of Historic Places possess a significant concentration , linkage, or continuity of sites, buildings, structures, or objects united historically or aesthetically by plan or physical development. Established in 1979 and administered by the Division for Historic Preservation, the Vermont State Register is an essential tool for the evaluation and protection of Vermont’s historic and archaeological resources. This data-set DOES NOT contain information about properties that are individually listed in the State Register of Historic Places. Learn more about the Vermont State Register of Historic Places.

How do I update a survey when a new one is available?While the Survey123 app will notify you and update it for you, we've experienced some select-one questions having duplicate choices. It's a best practice to delete the old survey and download the new one. See this document for step-by-step instructions.I already have an ArcGIS member account with my organization, can I use it to complete MRGP inventories?Yes! The MRGP solution is shared within an ArcGIS Group that allows outside organizations. Click "join this group" and send an request to the ANR GIS team. This will allow you complete MRGP requirements for the REI and stay logged into your organization. Win-win situation for us both!AGOL Group: https://www.arcgis.com/home/group.html?id=027e1696b97a48c4bc50cbb931de992d#overviewThe location where I'm doing inventory does not have data coverage (LTE or 4G). What can I do?ArcGIS Field Maps allows you take map areas offline when you think there will be spotty or no data coverage. I made a video to demonstrate the steps for taking map areas offline - https://youtu.be/ScpQnenDp7wSurvey123 operates offline by default but you need to download the survey. My recommendation is to test the fieldworker solution (Steps 1-5) before you go into the field but don't submit the test survey.How do remove an offline area and create a new one? Check out this how-to document for instructions. Delete and Download Offline AreaWhere can I download the Road Erosion Scoring shown on the the Atlas? You can download the scoring for both outlets and road segments through the VT Open Geodata Portal.https://geodata.vermont.gov/search?q=mrgpHow do I use my own map for launching the official MRGP REI survey form? You can use the following custom url for launching Survey123, open the REI and prepopulate answers in the form. More information is here. TIP: add what's below directly in the HTML view of the popup not the link as described in the post I provided.

How do I save my name and organization information used in subsequent surveys? Watch this short video or execute the steps below:

Open Survey123 and open a blank REI form (Collect button) Note: it's important to open a blank form so you don't save the same segment id for all your surveys Fill-in your 'Name' and 'Organization' and clear the 'Date of Assessment field' (x button). Using the favorites menu in the top-right corner you can use the current state of your survey to 'Set as favorite answers.' Close survey and 'Save this survey in Drafts.' Use Collector to launch survey from selected feature (segment or outlet). Using the favorites menu again, 'Paste answers from favorite.

What if the map doesn't have the outlet or road segment I need to inventory for the MRGP? Go Directly to Survey123 and complete the appropriate Road Erosion Inventory and submit the data to DEC. The survey includes a Geopoint (location) that we can use to determine where you completed the inventory.

(Link to Metadata) This data set is a digital soil survey and generally is the most detailed level of soil geographic data developed by the National Cooperative Soil Survey. The information was prepared by digitizing maps, by compiling information onto a planimetric correct base and digitizing, or by revising digitized maps using remotely sensed and other information. This data set consists of georeferenced digital map data and computerized attribute data. The map data are in a soil survey area extent format and include a detailed, field verified inventory of soils and miscellaneous areas that normally occur in a repeatable pattern on the landscape and that can be cartographically shown at the scale mapped. A special soil features layer (point and line features) is optional. This layer displays the location of features too small to delineate at the mapping scale, but they are large enough and contrasting enough to significantly influence use and management. The soil map units are linked to attributes in the National Soil Information System relational database, which gives the proportionate extent of the component soils and their properties.

Point feature class representing historic locations of elevation benchmarks, cross-cut marks, etc. Many of these historic marks have been destroyed by subsequent construction and maintenance of streets, curbs, sidewalks, etc. These so-called benchmarks are strictly elevation marks at best, rather than precise x,y locations. These elevation mark features are no longer maintained by the City of Dallas, but may have some utility in utility construction, when they can be found. No meaningful field work has been done on these marks since 2010. No meaningful inventory of existing versus destroyed marks has been done since 2014. There was an intent for City of Dallas Public Works Survey to set a significant number of new elevation benchmarks in approximately 2010, but this effort was ultimately abandoned.

This web map contains data featuring historic resources, districts and historic survey reports (Points, Lines, and Polygons) in Texas. These include State Antiquities Landmarks (SALs, Architecture only), National Historic Landmarks (NHLs), National Register of Historic Places resources (NRHP Listed, NRHP Eligible, Recorded Texas Historic Landmarks (RTHLs), and whenever possible Contributing properties as well as locally designated historic features.

The data set consists of 1:25,000 topographic maps covering Lutzow-Holm Bukt coast and major bare rock areas and inland mountains. The contour interval is 10 m. Maps of Lutzow-Holm Bukt coast were published in 1965 - 1986, and those of Prince Olav coast in 1974 - 1985. Total number of map sheets for these areas is 61. Maps of Yamato Mountains were published in 1980 with 11 sheets. All maps have been digitized into raster data and are available with TIFF format.

(Link to Metadata) NRCS mapped historical and current-day built-up lands for Grand Isle County, VT using several vintages of aerial photography: 1941, 1962, 1974, 1977, 1980, 1986, 1995, and 2003. The mapping was done using definitions and protocols established by NRCS in its conduct of the National Resources Inventory (NRI), a statistically based survey, designed and implemented to assess the conditions and trends of soil, water, and related resources on non-federal lands. Two land cover/use categories from the NRI ("urban and small built-up" and "farmsteads") were combined and mapped as 'Built-up'. NRI minimum built-up densities were not adhered to. In addition, total 'developed' lands for 2003 were mapped by integrating the mapped built-up data with roads, both public and private. An approximate 15-page report on definitions, mapping tools and ancillary materials, mapping methodology, and results is included with the data distributed by VCGI. Prepared results include tabular information on built-up change for the County and each of its five towns, 2003 road data, and a graphic depicting built-up acreage changes from 1941-2003. See Builtup_Documentation.doc & Builtup_Prepared_Results.xls included with the data zip file. VCGI converted the orginial NRCS shapefiles to Arc/Info coverage region subclasses. The region naming convention for built-up data is: region.b, for the developed 2003 data the naming convention is: region.dev2003. This "feature dataset" approach allows multiple data sources to be treated as one data set.

Forest Ecosystem Dynamics (FED) Project Spatial Data Archive: County Soil Survey Data with Attributes

The Biospheric Sciences Branch (formerly Earth Resources Branch) within the Laboratory for Terrestrial Physics at NASA's Goddard Space Flight Center and associated University investigators are involved in a research program entitled Forest Ecosystem Dynamics (FED) which is fundamentally concerned with vegetation change of forest ecosystems at local to regional spatial scales (100 to 10,000 meters) and temporal scales ranging from monthly to decadal periods (10 to 100 years). The nature and extent of the impacts of these changes, as well as the feedbacks to global climate, may be addressed through modeling the interactions of the vegetation, soil, and energy components of the boreal ecosystem.

The Howland Forest research site lies within the Northern Experimental Forest of International Paper. The natural stands in this boreal-northern hardwood transitional forest consist of spruce-hemlock-fir, aspen-birch, and hemlock-hardwood mixtures. The topography of the region varies from flat to gently rolling, with a maximum elevation change of less than 68 m within 10 km. Due to the region's glacial history, soil drainage classes within a small area may vary widely, from well drained to poorly drained. Consequently, an elaborate patchwork of forest communities has developed, supporting exceptional local species diversity.

Additionally, almost 450 ha of the surrounding area consists of bogs and other wetlands. Generally, the soils throughout the forest are glacial tills, acid in reaction, with low fertility and high organic composition. These soils are classified primarily within three suborders: orthods, orchrepts, and aquepts. The climate is chiefly cold, humid, and continental and the region exhibits a snowpack of up to 2 m from December through March.

The original soil polygons were obtained by digitizing a 1963 USDA General Soil Map of Penobscot County, Maine. All of the soil symbols used were taken directly off of the county soil map. Data from the State Soil Geographic Database (STATSGO) were cross-matched. The county symbol was chosen as the identifier, and a STATGO identifier that best "fits" the county soil identifier was selected. The original maps used for the digitization came in 6 map sheets. All of the sheets were digitized, corrected, edge-matched, and appended. Once this was finished, topology was built, new items and attributes were added.

The data in its current form can be used to delineate basic soil groups. However, because the STATSGO map unit identifier is located in each polygon the user can link any of the other STATSGO data sets depending on the desired information. The identifier is the key for creating a very detailed and thorough soils data set. Once linked the data can be used for ecological modeling, resource management, and many other applications.

A compilation of bedrock outcrops as points and/or polygons from 1:62,500 and 1:24,000 geologic mapping by the Vermont Geological Survey, the United States Geological Survey, and local colleges and universities between 1950-2016.Data was included as points or polygons based the source data.Includes data from VGS Open File Reports, VGS Bulletins, USGS reports, digitized 1:62,500 surficial and bedrock maps, student MS and PhD theses, and some unpublished data.For each point or polygon the NAD 1983 UTM Zone 18N X and Y coordinates are included (for polygons it is the X and Y coordinates of the centroid).A reference and publication year are included when possible.Compiled in January, 2017.
