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 »

myNewYorkviewer: Integrating TNM Services with Local Data

The ESRI ArcGIS Explorer (AGX) desktop viewer provides an excellent environment to mash-up geospatial datasets from authoritative federal, state, and local sources. Highlighting several TNM map services, the myNYviewer integrates a range of live state (NY and PA) and county government map services, including local geospatial datasets. The mash-up focuses on the Marcellus Shale gas development in the Southern Tier region ...more »

Using TNM for contributing to OpenStreetMap

OpenStreetMap (OSM) is a wiki-like map of the world. Public domain data is an important information source for OSM. While many layers from TNM have been uploaded in bulk to OSM, many have not. TNM layers are provided as cached tiles and WMS layers that, with a little effort, can be used to digitize features directly into OSM.

Use of TNM Data to Detect Significant Topographic Changes

TNM data (elevation and land cover) have been used to develop a national inventory of significant topographic changes in the U.S. TNM elevation data (National Elevation Dataset) and Shuttle Radar Topography Mission (SRTM) data form a unique pair of seamless multi-temporal elevation datasets that were analyzed to detect 20th century topographic surface changes. An extensive Web site ( http://topochange.cr.usgs.gov/ ) ...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.
