These are the types of layers supported by GeoAgro GIS, as well as those unsupported and what to do when an issue related to the layers comes up.

GeoAgro GIS Supported Layer Types:

GeoAgro GIS supports raster and vector layers.

Raster layers

These layers contain imagery. No attributes or structures are associated. E.g.: satellite imagery.

Vector layers

Vector layers may be:

  • Polygons
  • Lines
  • Points

These layers usually are associated to a data structure.

Polygon layers

Features in these layers are poylgons. They must feature at least 3 nodes. E.g.: fields, zones, prescriptions, etc.

Lines layers

Items in this layer are lines and curves. They must feature at least 2 nodes. E.g.: Roads, streams, GPS tracks, contours, etc.

Points layers

Items in these layers are points. Each point is identified as a single node. E.g.: Input application, yield, soil samples, etc.

Layers unsupported by GeoAgro GIS:

  • Mixed: These kind of layers may include, in the same layer, items of different kinds such as polygons, points and lines. Such layers cannot be used in GeoAgro GIS.
  • Multi point: These kind of layer can associate several different points to a single attribute entry. Please review your GIS software manual to see how to convert these kind of multipoint shapefile to a regular point shapefile.

Issues with GeoAgro GIS:

  • Damaged: When GeoAgro GIS finds a "DaƱada" layer, it may be due to a broken shapefile. If the shapefile was downloaded from the internet or via email, please try again with th download. If the problem's still there, ask about it to the provider of the damaged file.
  • Unknown: A layer is considered Unknown if GeoAgro GIS cannot classify it among any of the aforementioned types. If the layer type is unkonown, it won't be able to be be used in GeoAgro GIS
