Geologic Map of North America with The National Map base map

http://bit.ly/m97DmX This multi-scale geologic map service is a partial representation of the digital data for the Geologic Map of North America. Geologic units and faults, clipped to the terrestrial extent of North America, are represented here. The major divisions of geologic time (stratigraphic age) are represented with the RGB equivalent of the CMYK color specifications presented in the FGDC Digital Cartographic ...more »

NRCS Soils with TNM Basemap

http://bit.ly/kHLJvX This map uses The National Map base map from the USGS to shows the Soil Survey Geographic (SSURGO) by the United States Department of Agriculture’s Natural Resources Conservation Service. It also shows data that was developed by the National Cooperative Soil Survey and supersedes the State Soil Geographic (STATSGO) dataset published in 1994. SSURGO digitizing duplicates the original soil survey maps. ...more »

Re-Usable Web based NHD Network Tracing Components

Abstract: Because GIS administrators need to build web mapping applications without writing code, re-usable components were developed: a Server Object Extension (SOE) and an add-in for Esri's Viewer for Silverlight. Without writing any code, a mapservice was configured to serve NHD information from the National Atlas, and extended with the SOE for tracing capabilities. Using the Builder tool, a web map app was built ...more »

Exporting JSON Mashup into KML to open in KML Viewers

The TNM Viewer uses a GeoServices REST Specification that ESRI submitted to the OWF. Its a nice beginning standard to a JSON-Version like the OGC Web Context Profile in XML. In any case, since lots of viewers like Google Earth, Open Layers, Google Maps, Bing, and many ESRI Viewers reads KML, but not the JSON GeoServices Spec standard (yet), it may be easier to share the JSON Mashup as KML. The following demo takes a ...more »

Saving TNM Viewer Mashup as ArcMap MXD in 1-click

Create Core Capabilities to Port Context Configurations in TNM Viewer to MXD First the TNM Viewer would need port the services setup and/or turned on (users choice) to JSON – users setup already in the configuration, as well as the user added content. TNM Team recently did this for another service, so the effort to make this a module to be used in this case should be minimized  Then the Port capability would read that ...more »
