I'd like you to make downloading, implementing, and sharing the output of, this felt-tastic style your new highest priority.So what do you get when you download this style, besides a rush of craft-induced adrenaline? These symbols...I've seeded the style with some pre-colored symbols but each and every one of these felty symbols can be dyed whatever color you want in the symbology panel. Here are some example maps using this style...Happy Mapping! John Nelson

These data display the felt effects for selected historical California earthquakes. By selecting a linked earthquake you can see a map of the area and intensity of shaking from that earthquake. Then by clicking on a city on the intensity map (or list beneath the map) you can see what that location reported after the earthquake. These “felt reports” are usually from newspapers during the 1850 to 1930 time period. The felt reports were compiled and published in 1981* and 1982** with updates added through the years. Not all earthquakes have intensity maps and felt reports online since the conversion from printed report to web page is an on-going process. Most of the San Francisco Bay area events between 1838 and 1906 are finished.More information is available in the California Geological Survey publication: Map Sheet 49 and Department of Conservation - Earthquake Catalogs.*Toppozada, T.

Delta Primary Zone Boundary The history of the primary zone boundary is as follows: the Primary Zone was defined in the 1992 Delta Flood Protection Act by referring to a map attached to the legislation, on file with the Secretary of State. See Public Resources Code section 29728. The map was submitted by the Delta Protection Commission. It is a large extent (small scale) map, with no real controls, little or no reference marks or guides of any kind, and no legal description. As such, from a mapping point of view, it leaves much to be desired. Nevertheless, by law, this map defines the Primary Zone boundary. Sometime shortly after the law was passed, DWR Land & Right of Way drew the boundary on 24k topo maps which also had the precise, agreed-upon legal Delta boundary. There are some significant differences between the DWR version and the official version. In asking current DWR Land & Right of Way staff (Carrol Leong & Fred Mau), there was no readily-available explanation, and the person who originally conducted it is no longer there. That is unfortunate, because not only are these maps much more "accuracy friendly", but there may have been good reasons why the boundary was drawn as such. This is the Delta primary zone boundary. It was drawn by Joel Dudas on November 27, 2002, as described below. It was drawn at the request of Margit Arambru, Delta Protection Commission. The legal Delta/primary zone effort conducted by Chico State had raised questions about the primary zone boundary, and upon inspection of the issue it has been determined that there is no precise solution available at this time. Lori Clamurro & Margit Arambru indicated that this delineation was acceptable to them upon review (12/8/2002). METHOD: There were significant errors in the paper base map, as evidenced by errors in the locations of roads, watercourses, and the legal Delta boundary itself. Due to these significant problems posed by the errors inherent in the paper base map, the base map was used as a guide, rather than as a literal translation, to locate the primary zone boundary. Furthermore, a second significant assumption was made, namely that the intent of the Primary Zone map was to indicate that the legal boundary and the primary zone boundary are one and the same in many places, but that mapping this would not result in distinguishable lines if they were literally drawn atop each other, and they therefore were lined up adjacent to one another (on the source paper map!), with the gap being as small as possible but also being far enough apart to clearly distinguish the two lines. Therefore, for GIS purposes, the shapefile was created by tracing the legal boundary line wherever this was felt to be appropriate. The third major assumption was that, in places where the primary zone and the legal boundary are separated, the primary zone boundary was equivalent to the primary zone boundary drawn by DWR Land & Right of Way on the higher accuracy 24k maps in all places except where significant deviations obviously occurred as indicated by the official paper base map. The rationale for this is that the 24k map does a better job delineating the boundary according to actual features (watercourses, rec district boundaries, etc.) where the intended boundary was clearly the same, but where the paper map simply cannot represent this intent accurately. However, in places where the intent clearly shows a discrepancy from the "higher accuracy" line, the boundary on the paper base map was literally traced. Delta Secondary Zone Boundary The parent of this file was one of the Delta Vision Status & Trends shapefiles. Published in 4/2007. The change to the boundary near Van Sickle was made subsequent to delivery to DWR on 10/8/2009. Also, offsets versus the legal Delta boundary were corrected by DWR on 10/22/2009. At this time, unless better information becomes available, it is therefore felt that these are the best boundaries available.

This map is an approximation of the level of stress felt by the users of the roadway and is determined by the number of lanes, traffic volumes and vehicle speeds.

The files linked to this reference are the geospatial data created as part of the completion of the baseline vegetation inventory project for the NPS park unit. Current format is ArcGIS file geodatabase but older formats may exist as shapefiles. In 2009, the National Park Service (NPS) Vegetation Mapping Inventory funded the NPS South Florida Caribbean Network (SFCN) to evaluate the accuracy of a vegetation map produced by the University of the Virgin Islands (UVI) Eastern Caribbean Center, Conservation Data Center for Virgin Island National Park (VIIS). The UVI vegetation map of VIIS was completed in 2001 and was based on aerial imagery from 1994. VIIS park staff felt that the UVI vegetation map was relatively accurate, but recognized that no formal accuracy assessment of the product had occurred at the time of its creation. Both the UVI and SFCN vegetation maps of VIIS relied on aerial imagery and photo-interpreters to delineate vegetation communities. However, the SFCN vegetation map had the benefit of having LiDAR data available; a technology and data source not readily available when the UVI vegetation map was produced. In addition, the SFCN vegetation map benefited from technological advances in aerial image acquisition that significantly improved the quality and resolution of imagery used; GPS that allowed precise spatial location determination; and GIS science that permitted the viewing, layering, and manipulation of multiple data sources simultaneously. The SFCN vegetation map also benefitted from the use of digital orthophotographs that take into account the surface elevation, topography, of the earth and camera tilt. The UVI vegetation map has an estimated map accuracy of 45.9% with a lower 90th Percentile Confidence Interval of 38.5% while the SFCN vegetation map accuracy is estimated at 87.9% with a lower 90th Percentile Confidence Interval of 82.0%. The SFCN vegetation map has approximately 2.1 times more detail, in the form of individual patches, than the UVI vegetation map does, 1,430 vs 686 patches, respectively. Mean patch size and maximum patch size are smaller in the SFCN vegetation map than in the UVI vegetation map. This results in the SFCN vegetation map being less homogeneous than the UVI map even though the total number of community types mapped are nearly identical, 27 vs 29.

This displays recent earthquake information from the United States Geological Survey (USGS) Prompt Assessment of Global Earthquakes for Response (PAGER) program.In addition to displaying earthquakes by magnitude, this web map also provides earthquake impact details. Impact is measured by population as well as models for economic and fatality loss. For more details, see: PAGER Alerts.Events are updated as frequently as every 5 minutes and are available up to 30 days with the following exceptions:Events with a Magnitude LESS than 3.0 are retained for 3 daysEvents with a Magnitude LESS than 4.5 are retained for 7 daysIn addition to event points, ShakeMaps are also provided. These have been dissolved by Shake Intensity to reduce the Layer Complexity.The specific layers provided in this service have been Time Enabled and include:Events by Magnitude: The event’s seismic magnitude value.Contains PAGER Alert Level: USGS PAGER (Prompt Assessment of Global Earthquakes for Response) system provides an automated impact level assignment that estimates fatality and economic loss.Contains Significance Level: An event’s significance is determined by factors like magnitude, max MMI, ‘felt’ reports, and estimated impact.Shake Intensity: The Instrumental Intensity or Modified Mercalli Intensity (MMI) for available events.For field terms and technical details, see: ComCat DocumentationThis map is provided for informational purposes and is not monitored 24/7 for accuracy and currency.

Sammendrag (for English see below)

Dette geologiske kartet fra Norsk Polarinstitutt har blitt produsert med tanke på å brukes på smart-telefon, nettbrett eller PC uten nett-tilkobling, for eksempel til feltarbeid eller som et hendig oppslags-kart. Kartet består av 5 raster-filer i GIS-formatet JPEG2000 og er tilgjengelig som nedlasting fra datasenteret til Norsk Polarinstitutt

Informasjon om de geologiske enhetene er plassert som tekst-merkelapper direkte i kartbildet, i motsetning til en vanlig tegnforklaring. Ved å zoome inn på kartet finnes informasjon om geologiske enheter, vist med blå tekst (alder i parentes). I tillegg er hvert enhet (farge) merket med en tilsvarende 4-sifret kode i blå skrift.

I felten kan mobile dingser med GPS vise brukeren sin posisjon på kartet. Avhengig av skjermoppløsning er full detaljgrad i kartet synlig på ca. 1:30 000-skala, men kartet kan også vises på mye større skala for å se f.eks. regionale geologiske trekk.

Kartet kan vises på Android eller iOS-enheter med appen "Geoviewer" fra Extensis (tidligere Lizardtech). På datamaskin fungerer QGIS eller ArcMap bra for å vise kartet. Se forklaring på hvordan overføre kartet til din smart-telefon eller nettbrett lenger nede på sida.

Data

Kartet er laget ved å bruke data fra Norsk Polarinstitutt 1:250 000-skala geologiske kart for Svalbard, opprinnelig publisert i "Geoscience Atlas of Svalbard" av Dallmann (ed.) 2015. Dette kartet er generalisert fra 1:100 000-skala kart-data i hovedkartserien til Norsk Polarinstitutt, og er publisert i Geoscience Atlas of Svalbard (Dallmann 2015).

Til å produsere dette kartet er topografiske data fra S100 (topografi, vann) og S250 (kystlinje)-datasettene fra Norsk Polarinstitutt brukt. Fjellskygge er konstruert med S0 Terrengmodell med 20 meter pr. pixel oppløsning. Bre og snøflekk-områder er vist med datasettet for 2001-2010 av König mfl. (2013), som gir et mer oppdatert bilde av blotning-situasjonen nær breer og snøflekker. Områder der geologiske polygoner ikke er justert til nye blotninger er vist i brunt. Kystlinjen er i noen tilfeller endret for å tilpasses bre-fronter som ender i sjøen.

Forbehold om datakvalitet Dette er et nytt geologisk kartprodukt, og det kan forekomme feil. Spesielt tegnforklaring, som er skrevet direkte på geologiske enheter, kan være problematisk i noen områder. Vi er interessert i tilbakemelding på mulige forbedringer av kartet. Send gjerne tilbakemeldinger på e-post til Geokart@npolar.no.

Dette er et geologisk kart ment for å formidle vitenskapelige data, og er ikke egnet for navigasjon. Noen områder av Svalbard er ennå ikke kartlagt i detalj, og en del av dataene er av eldre dato, så datakvaliteten for dette kartet er varierende. Kartet kan inneholde feil i grunnlagsdata, kartpresentasjon, kartografi og tekst-beskrivelser. For en stor del er geologien kartlagt for en mindre detaljert skala enn den det er mulig å oppnå med dette kartproduktet, så geologiske trekk og enheter vil i ulik grad fremstå feilplassert ved bruk av god GPS-posisjon og detaljert zoom-nivå. Breer og spesielt bre-fronter er i konstant forandring, og selv om ganske oppdaterte data er brukt for å lage kartet, vil det være feil i en del bre-posisjoner. Vær oppmerksom på at det topografiske grunnlaget som er brukt her i mange tilfeller er av nyere dato enn det som opprinnelig var brukt under kartleggingen i felt. Dette kan også føre til feil i kartet.

Geologiske kart-data vil kontinuerlig være gjenstand for re-tolkning og endring. For en full beskrivelse av kartleggingsprogrammet ved Norsk Polarinstitutt, geologiske kart-data presentert her og referanser, se Dallmann (ed.) 2015, eller besøk npolar.no

Geological map of Svalbard (1:250 000).

Abstract This geological map from the Norwegian Polar Institute has been prepared to be used offline on a smartphone, tablet or computer, for example for field work or a handy reference. It consists of 5 raster-files in the JPEG2000 GIS-format, available to download from the Norwegian Polar Institute data centre data.npolar.no via https://data.npolar.no/dataset/eafafbb7-b3df-4c71-a2df-316e80a7992e/.

Information about the geological units has been placed as text labels (in blue typescript) directly on the map, as opposed to a regular legend. By zooming in, information about each geological unit on the map can be found, shown in blue text (age in parentheses). In addition, each unit is labelled with a corresponding 4-digit code also in blue typescript.

In the field, GPS-enabled devices can show the user's location on the map. Depending on screen resolution, full detail of the map (including text labels) is best viewed at ca. 1:30 000 scale, but the map can also be viewed at much larger scales to see e.g. regional geological features.

For mobile use, the app "Geoviewer" from Extensis (formerly Lizardtech) can be used. On a computer, QGIS works well to view these maps. See an explanation below on how to transfer the map to your tablet or smartphone.

Data

The map is made using data from the Norwegian Polar Institute 1:250 000-scale geological map for Svalbard, originally published in Dallmann (ed.) 2015. This geological map has been generalised from the 1:100 000-scale main map series published by the Norwegian Polar Institute, and is published in Geoscience Atlas of Svalbard (Dallmann 2015).

For the purpose of this map product, topographic data from the Norwegian Polar Institute S100 Map (topography, water) and S250 (coastline) data sets have been used. Hill shade was created using the NPI S0 Terrengmodell at 20 meters/pixel resolution. Glacier and snow patch outlines are shown using the 2001-2010 dataset of glacier area outlines for Svalbard by König et al. (2013), which gives a more up to date picture of the outcrop situation near glaciers or snow patches. Areas where geology polygons have not been re-adjusted to the new outcrops are shown in brown. The coast line-data has been adjusted in some cases to adapt to glacier fronts ending in the sea.

Disclaimer This is a new geological map product, and errors may occur. In particular the legend, which have been printed directly on the geological units, can be problematic in places. We appreciate feedback on the map that can be used to improve the map in future versions. Please email feedback to Geokart@npolar.no.

This is a geological map meant to convey scientific data, and is not suited for navigation. This map product may contain errors in base data, map presentation, cartography and text descriptions. Much of the geology was originally mapped for a less detailed scale than what is possible to obtain with this map, so geological features will to varying degrees appear out-of place when a good GPS-position and detailed zoom level is used. Glaciers and in particular glaciers fronts are dynamic features, and although using fairly up-to-date data, this map does contain errors in glacier front positions. Note that the topographic base data used here in many cases is of a newer vintage than the data originally used for geological mapping in the field. This may cause some errors in the map. Some areas of Svalbard have not yet been mapped in detail and some of the data are of older origin, so the data quality presented on this map is variable.

Geological map data will be subject to continual re-interpretation and editing. For a full description of the bedrock mapping programme at the Norwegian Polar Institute, the geological map data presented here and
