ESRI Shapefiles
Shapefiles are a multi-file format, with each file containing some specific data. Three file parts are mandatory (
.shp, .shx and .dbf) and, without any of them, your upload will not be successful.A fourth component (
.prj) is very common, and used to determine what Spatial Reference System should be used to interpret the coordinates in your data. If this file is not present, Felt will assume the coordinates are in latitude/longitude (represented by the EPSG code 4326).Spreadsheets
See the Working With Spreadsheets page for general information on tabular file formats like CSV or Excel.
Point coordinates
- Coordinates must be in latitude and longitude. Other coordinate systems, such as UTM, are not supported.
- Coordinates must be in numeric format, such as 40.7128 or -74.006. Felt cannot parse coordinates with text characters, such as 40° 43' 50.1960'' N or 74.0060° W.
- Coordinates must be in two separate fields.
Geocoding
See the Geocoding Addresses page for general information on how Geocoding works.
- Context is important. Make sure either your
addressfield contains all the necessary information (city, state, country, etc) or you have several fields with that information.
Geomatching
See the Geomatching Regions page for general information on how Geomatching works.
