1Geo Data is a data of the routes, the track logs and the waypoints.
 
You can upload recorded routes by GPS-tracker to the GIS Viewer. View Geo Data of your activities (run, walk, hike, drive) by yourself or share the result with your co-workers, your family and your closest friends even if you are far away from each other.
All you need is a GIS file in any of the supported formats:
  • gpx
  • kml, kmz
  • geojson, json, topojson
  • shp, dbf, shx, cpg, prj, qix
  • mif, mid
  • tab, map, id, dat
  • gdb, gdbtable, gbdtablx
  • gml
  • osm
  • csv

TOPOJSON TopoJSON

TopoJSON is a GeoJSON extension that encodes topology. JSON based format designed to represent the geographical features with their non-spatial attributes. This format defines different JSON (JavaScript Object Notation) objects and their joining fashion. JSON format represents a collective information about the Geographical features, their spatial extents, and properties.

how to

How to convert TopoJSON to PDF

  • Drop/upload a GIS file or select it from your cloud storage.
    !The remaining rendering parameters can be left as default. In this case go to step 6.
     
  • Select the render format from the drop-down list (the default format is PNG)
  • Select the render scale (the default scale is medium)
  • Select the Map reference system2 (the default system is Wgs84).
    Use a popular spatial reference system from a list or choose a custom system to enter the functioning EPSG code (4–5-digit numbers that represent coordinate reference system definitions) by yourself.
    We recommend choose "Undefined" to avoid repeated redefinition of the coordinate system (SRS).
    2Map reference system is a planar coordinate system that defines how the 2D projected map in your GIS relates to real locations on the Earth.
     
  • The GIS Viewer allows the user to adjust Map Rendering Settings for the most accurate result:
    - Map Width and Map Height are for setting the exact dimensions of the render scale,
    !In contradistinction to the three preset scales from point 3.
     
    - Padding is a padding from the edges of the image(map),
    - Warp Height and Warp Width are for changing the resolution of a raster image(map),
    - Extent.XMin, ExtentXmax, extent.YMin, Extent.YMax are to specify the bounds of a map to render. If no values are set, GIS Viewer automatically adds all objects from the GIS file to the rendered map.
  • Click the "Generate" button after all – GIS Viewer quickly processes and displays Geo Data on the screen. You can change the position and the scale of the rendered map with a computer mouse.
  • Click the "Download" to download the rendered file to any device, you can also save it to the cloud storage Drop Box or Google Drive by click the relevant links.
