This map tool supports drag-and-drop adding of GPX, GeoJSON, IGC, KML, and TopoJSON data.
If you have a zipped shapefile, you can upload it to our service (below) to receive a converted geoJson file.
- before selecting for upload, please make sure your shapefile name does not contain spaces
- Your shapefile will be converted to GeoJson format and given a default name for saving to your device; you can rename it after download but we recommend you do not change the file extension
- Once you've downloaded the converted file (and optionally renamed it) you can drag it onto the map to visualize your layer in this context.
Printing Tips
- Use the browser's "Print Preview" to fine-tune the map layout options.
- Depending on the map area in view, selecting "landscape" print mode may result in a larger and more useful map image.
- If the map appears distorted in the print preview (or actual print), resizing the whole browser window to the approximate height/width ratio of your sheet of print paper before selecting "print" or "print preview" may help to produce a less distorted map image.
- Internet Explorer compatibility settings could interfere with map printing; IE browsers should be set to use "Edge" rendering mode for best performance.
- Any information boxes, layer controls, or legends visible on-screen will appear on the printed output, below the main map; close unneeded panels and info boxes before printing.
The button below may bypass the Browser's preview options; use the appropriate Browser menu to review in preview mode before printing.

Select data by parameters, grouped locations, and years. This method selects data for download only: points will not change on the map. For visualization options, select ‘Filter/Visualize/Download’ above instead.
Data rows are selected using an “OR” query among parameters, meaning rows with any selected parameters will be included in results.
Filter data by parameters, grouped locations, and dates; visualize the results of filtering as points change on the map.
After filtering, the Data Explorer panel’s Download tab allows the retrieval of all selected results in csv (Excel-compatible) format.
For visualization purposes, data rows are selected using an "AND" query among parameters, meaning all selected parameters must have a value to be included in the results.
