Digitizing used run length encoding techniques, sampling along horizontal lines which represented the midline of cells with a height of 250 ft. The horizontal measurement increment along these lines was one decafoot (10 feet). Additional details of the digitizing process are available on request. The coverage was subsequently converted to an Arc/Info vector format.

Download .zipA potentiometric surface map is a contour map that represents the top of the ground water surface in an aquifer. The contour lines illustrate the potentiometric surface much like the contour lines of a topographic map represent a visual model of the ground surface. A potentiometric surface map is very similar to a water table map in that both show the horizontal direction and gradient of ground water flow.Contact Information:GIS Support, ODNR GIS ServicesOhio Department of Natural ResourcesDivision of Geological Survey2045 Morse Rd, Bldg I-2Columbus, OH, 43229Telephone: 614-265-6693Email: gis.support@dnr.ohio.gov

An extreme flood in 2016 caused widespread culvert blockages and road failures across northern Wisconsin, including extensive damage along steep tributaries and ravines in the Marengo River watershed. Along with the flooding, there were fluvial erosion hazards (FEH) associated with a large amount of erosion in headwater areas. Of special concern were FEHs associated with gullying, loss of wetland storage, and valley-side mass wasting. In 2020, a pilot study was begun to map and classify ephemeral and perennial streams and wetlands in terms of their susceptibility to fluvial erosion hazards. This study combines rapid geomorphic field assessments of river corridor erosion and coupled sediment and debris delivery with mapping geomorphic vulnerability zones in a Geographic Information System (GIS). The FEH assessment results will ultimately be used to identify and prioritize natural flood management projects related to stream and wetland restoration.

The CAUV's of land are computed using soil characteristics and production information contained in Bulletin 685, Cooperative Extension Service, The Ohio State University, dated July 1983, and entitled "Ohio Soils with Yield Data and Productivity Index." CAUV figures were obtained from the land tables for tax years 1984, 1985, and 1986, Tax Equalization Division, Ohio Department of Taxation, 1983.

Soils used in this analysis were digitized from the paper original soil survey sheets. These sheets were taped together to form an area covering each of the USGS 7.5 minute quadrangle maps in the county. The areas for each quadrangle were then digitized using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet. The measurement increment along these lines was one decafoot (10 feet). The quadrangle files were then merged into a county file which has subsequently been converted to Arc/Info format.

The user should bear in mind that this coverage is only an approximation of the soil survey and should not be used for site specific analysis.

Updated Weekly*This data set represents tax lots for Jackson County and includes account info (ownership, assessed and real market values, and building information). Data is updated on a weekly basis from assessor tax parcel information. Where there are several different owners on an individual parcel, multiple parcels polygons will exist since parcel to ownership is not a one to one relationship. Some other fields like year built are populated with the first record if multiple exists. For question about parcel updates or issues please contact the Assessor's Office at (541) 774-6059.

Updated regularly* Building footprints are polygon features which represent structures in Jackson County. The layer is maintained by several different organizations in Jackson County including the City of Medford and the City of Ashland. These organizations building footprint data along with footprint information from several Jackson County departments is incorporated into this layer representing the best information about building footprints in the County.

Download .zipThis coverage was extracted from the 1994 statewide land cover inventory of Ohio produced by Bruce R. Motsch and Gary M. Schaal of the Ohio Department of Natural Resources.

The land cover inventory for the State of Ohio was produced by the digital image processing of Landsat Thematic Mapper Data. The Thematic Mapper is a multi-spectral scanner that collects electromagnetic radiation reflected from the earth's surface in the visible, near infrared and mid-infrared wavelength bands. The resolution of the Thematic Mapper data is a 30 meter by 30 meter cell. The computer analysis of the data isolates unique spectral classes that relate to land cover characteristics.

The land cover inventory was produced from Thematic Mapper data acquired in September and October 1994. The data was classified into the general land cover categories of urban, agriculture/open urban areas, shrub/scrub, wooded, open water, non-forested wetlands and barren.

The land cover information reflects the conditions of the satellite data during the specific year and season the data was acquired. The Thematic Mapper data was processed using ERDAS image processing software. The data was originally created in raster format and georeferenced to Universal Transverse Mercator (UTM) zone 17 coordinates NAD27. The data can be combined with other georeferenced digital data layers.

The data is also available in its original ERDAS image format.

Download .zipThis map was derived from the Ashland County Soil Survey using the Universal Soil Loss Equation to calculate estimated erosion rates from soil with no till management systems. Land use data from 1982 aerial photography was utilized in the analysis to determine land not suitable for cultivation. a no till management system assumes a no till corn-no till corn-no till soybean-small grain-meadow-meadow rotation. Soil erosion rates were then compared to "T", the tolerable soil loss rate for the soil type.

Factors combined by the universal soil loss equation include: rainfall factor, ersosion factor "K", and slope length and steepness factor.

Soils used in this analysis were digitized from the paper original soil survey sheets. These sheets were taped together to form an area covering each of the USGS 7.5 minute quadrangle maps in the county. The areas for each quadrangle were then digitized using run-length encoding technique sampling along horizontal lines which represented the midline of cells with a height of 250 feet.

Jackson County is comprised of 3 ambulance service providers each responsible for dispatching to a specified area known as an Ambulance Service Area (ASA). In the past, the ASA boundaries were somewhat arbitrary and regularly split taxlots. The lack of distinction between one ASA and another created a situation where two service providers would respond to the same residence from opposite directions. In the spring of 2008, the task of re-digitizing these boundaries was given to Karim Naguib at Jackson County GIS Services. There were three things that needed to be kept in mind while reproducing the ASA boundaries. 1) Maximize response times 2) Minimize overlapping responses 3) Make sure the boundaries were divided fairly To maximize response times it was important to consider access issues. In the previous ASA boundary, there were a handful of site addresses where a service provider would have to drive into another ASA and then double back to their own ASA in order to access a residence in distress. This issue lowered response times for the service providers and caused some confusion as to who the proper responder should be. The fastest way to isolate these issues was to display driveways from Jackson County GIS Services driveways layer. To minimize overlapping responses, it was important to make sure that there were very distinct boundaries between each of the ASA's. To complete this task, the previously existing ASA boundary was taken and the lines were followed throughout the entire county, and snapped to taxlot lines and vertexes rather than simply drawing them freehand style. It was during this process that the driveways layer was incorporated, making sure that where there was a confliction between taxlots, the service provider with the best access would get the response. The end result was a neat ASA boundary that matched taxlot boundaries. In order to make sure the boundaries were divided up evenly between the three providers, it was apparent that Jackson County GIS Services could not make the final decision. The first step to ensure this goal was met was to contact Gary Stevens at Jackson County Health and Human Services (our primary contact on this project). After email communications back and forth between Gary and Karim, in an attempt to talk each other through their ideas of how the ASA's should be drawn, they decided to meet face to face with representatives from each of the three service providers to make sure that everybody agreed on where the boundaries should be drawn. With representatives from Mercy Flights, Ashland Fire and Rescue, and the Rogue River Fire Department, as well as Gary Stevens present, the new ASA boundaries were edited in real-time. As the discussions were taking place, the lines were being re-digitized to match what the providers had agreed upon. Once all of the discussion had ended, the boundary was reviewed one more time to make sure that the changes were exactly what each provider had expected, and that each of them was happy with the outcome. After returning to the office, topology rules were created which were designed to point out mismatches in the lines of the ASA's. Where ever one ASA boundary crossed or did not perfectly overlap another, an error message would appear on the map showing exactly where the issue was. Once all of the errors were located and corrected, the topology rules were re-run to double check for accuracy.

Medford-Ashland Air Quality Maintenance Area (AQMA). Under the 1990 Clean Air Act Amendments, the Rogue Valley (Jackson County, Ashland, Phoenix, Talent, Medford, Jacksonville, Central Point, White City, and Eagle Point) became a nonattainment area for particulate matter (PM10). These communities shared a common airshed, known as the Medford-Ashland Air Quality Maintenance Area (AQMA). During the 1980s, particulate pollution in the AQMA reached some of the highest levels in the nation and violated the federal air quality health standards also known as National Ambient Air Quality Standard (NAAQS). This violation meant two things: 1. DEQ needed to write a plan to bring the Medford-Ashland AQMA back into compliance with the standard; and 2. Added restrictions would be placed on Rogue Valley communities to limit new and expanding industries and significant transportation projects would need to be reviewed to determine their compliance with the plan. The plan and rules addressing industry and residential woodstove curtailment were prepared by DEQ in 1991. The Environmental Quality Commission (EQC) adopted the plan and rules shortly thereafter. All the emission reduction measures adopted by the EQC were successfully implemented and air quality monitoring in the AQMA demonstrated that the PM10 standards were met in 1992. The Medford-Ashland AQMA currently meets the PM10 standards and EPA’s tougher new standards for fine particulate (PM2.5). On December 10, 2004, the EQC approved an updated PM10 attainment and maintenance plans. This plan continues all of the PM10 strategies from the 1991 attainment plan and continues the strictest requirements for managing emissions growth from future new and expanding major industry under the New Source Review program. EPA approved the plans in 2005. On 3-25-10, the Metes and Bounds legal description was reviewed to verify the county's records, and the AQMA was still accurate based on that definition.
