Leaflet and Google maps created by GPS Visualizer can now display ski trails from OpenSnowMap as a background map option. More 30m-resolution DEM elevation data has been installed on GPS Visualizer's server: new LIDAR-based files ("ODP1") for Iceland, and NASA SRTM1 data for Central America, the Caribbean, and northern Queensland. When tickmarks are added to a Google or Leaflet map, the "description" field of the tickmark will now contain the distance (for time-based tickmarks) or time (for normal distance tickmarks), if your input file contains the relevant data. If you create a Google or Leaflet map where the markers are displayed in folders in the marker list, you can use the gv_options.marker_list_options.folder_zoom parameter to automatically include a "zoom to contents" link next to the name of the folder. The JavaScript-based tool that can retrieve elevation data from the Google Maps Elevation API (using your Google API Key) has been updated so that it can look up 500 points at once this saves both time and calls to the API. GPS Visualizer's "NED1" collection of elevation data has been updated with the latest files from the US Geological Survey's 3D Elevation Program, which uses LIDAR to improve the accuracy of elevation data. GPS Visualizer now has basic support for Points, LineStrings, MultiLineStrings, Polygons, and MultiPolygons in GeoJSON (.json) FeatureCollection files. GPS Visualizer is based in Portland, Oregon, and has been on the Web since October 2002. xlsx),Īnd of course tab-delimited or comma-separated text.
