Farm management may require not just the work of a single person, but working in teams. In this case, you will need to exchange information among your peers; this tutorial will show you the different ways to exchange information and when to use them.

How do I exchange geographic data from GeoAgro GIS to GeoAgro GIS?

If everyone in your group uses GeoAgro GIS, the best way to exchange information is by using any of the two GeoAgro GIS native file formats:

  • .GIS files: These files are created when you backup all layers in a single project with the backup tool You are not allowed to choose which layers will be saved; all of the layers in the active project will be backed up. To transfer your backup to another computer, or to another project within the same computer, you need to use the [ restore backup tool]. Again, you are not allowed to choose which layers you will restore; all of them will be included.
  • .LAY files: These files are created when you backup one or more layers from a GeoAgro GIS project. This tool will allow you to choose which layers will be included in your .LAY backup file. When you restore these layers within a different GeoAgro GIS project, you will be prompted to answer which layers you'd like to restore, therefore, you do not need to restore all backup layers.


I have defined symbology for a layer. How do I apply it to other layers?

If you have defined symbology for a layer, you may apply it to other, similar layers by using the Export and Import Symbology tool.

This is especially useful when you want to define standards; by using this tool you may create a symbology library to reuse when necessary, for all layers in your GIS projects.


How do I exchange geographic data from GeoAgro GIS to other gis tools?

GeoAgro GIS enables you to export any layer in any project, so you can reuse them in other tools. GeoAgro GIS layers can be exported as shapefiles (.SHP files) or text files (.TXT files). You may also combine several layers and export them to georeferenced images (.JPGs,.BMPs,.TIFs,PNGs) or non-georeferenced images (.JPGs).


Shapefiles (.SHP)

GeoAgro GIS can export any layer in any GeoAgro GIS project to a standard shapefile, which can be used by other software tools such as ArcView, or Variable Rate Application machinery. The output are the three files which add up to a regular shapefile (an .SHP file, an .SHX file and a .DBF file).

GeoAgro GIS always uses a WGS84 geographic coordinate system (latitude/longitude), and any shapefile you export from GeoAgro GIS will also use geoagraphic coordinates.

Also, with GeoAgro GIS you may export a single/many layers or export only a layer's currently selected features

Text files (.TXT)

GeoAgro GIS can export points from a point layer, along with their data, to a tab delimited text file which can be imported by other applications. The output of this process will be a single .TXT file.

GeoAgro GIS always uses a WGS84 geographic coordinate system (latitude/longitude), and any text file you export from GeoAgro GIS will also use geoagraphic coordinates.

Google earth .kml/.kmz files

GeoAgro GIS can export layers to .kml files visible in Google earth, to facilitate distribution to other users with little or no GIS experience. See export to kml files.

Georeferenced image (.JPG, .BMP, .TIF, .PNG)

GeoAgro GIS allows to produce a georeferenced image based on the currently visible layers in your GeoAgro GIS window.

GeoAgro GIS will allow you to save the georeferenced image to one of this formats: .JPG, .BMP, .TIF y .PNG; and will automatically create the georeferencing file.

GeoAgro GIS always uses a WGS84 geographic coordinate system (latitude/longitude), and any georeferenced image you export from GeoAgro GIS will also use geoagraphic coordinates.

Not georeferenced image (.JPG)

GeoAgro GIS can produce a not georeferenced image based on the currently visible layers in your GeoAgro GIS window, which can be used by other applications (Microsoft Word, Microsoft Excel, Microsoft PowerPoint), sent by email o r be printed. You can produce such images with the printing tool.

As these images are not georeferenced, no georeferencing information will be exported.

How do I import data from other tools?

There are many other applications capable of producing georeferenced data. You may import into GeoAgro GIS standard shapefiles (.SHP files), tab delimited text files (.TXT files) and georeferenced images (.PNG, .TIF, .SID, .ECW, .JP2, .BIL, .JPG, .JPEG files).


Shapefiles (.SHP)

The ESRI Shapefile format was created by ESRI for their ArcView GIS tool, but it has become a standard format for exchanging geographic data between geographic information systems (GIS). Most GIS tools can export their layers to a Shapefile format.

Shapefiles always comprise at least three files (.SHP, .DBF, .SHX) and sometimes more (for instance, .PRJ). It's important to keep all these files always within the same folder before importing them into GeoAgro GIS with the import layer tool.

Even though when browsing for the shapefile with GeoAgro GIS you will only see the .SHP file, you need to keep your .DBF and .SHX all in the same folder with your .SHP file, otherwise GeoAgro GIS will not be able to import the layer.

Also, be aware that GeoAgro GIS uses the WGS84 geographic coordinate system; however you may also be able to import a shapefile that's set on a different coordinate system. If your shapefile also has information regarding its projection (it is always saved in a .PRJ file which should show up along your .SHP, .DBF y .SHX files), GeoAgro GIS will automatically convert the shapefile's coordinate system to WGS84 geographic coordinates. If there is no .PRJ file, GeoAgro GIS will chech if the shapefile is in WGS84 geographic coordinates and will import it. If it's not in geographic coordinates, a window will show up asking you to pick your shapefile's projection, so GeoAgro GIS can convert it to WGS84 geographic coordinates before importing it.


Text file format (.TXT)

Some GIS tools may export your GIS files to text files (.TXT files). GeoAgro GIS can import those files using the import text tool.

When you create these files, you must include your column headers, and they must be tab delimited. Currently, GeoAgro GIS only imports tab delimited files.

If you have a text file with a different delimiter, you need to modify your file first to convert delimiters to tabs before importing it into GeoAgro GIS (for instance, you may use the Replace tool in your Notepad)

Georeferenced Image (.PNG, .TIF, .SID, .ECW, .JP2, .BIL, .JPG, .JPEG)

GeoAgro GIS can import images or georeferenced photos into your GIS projects using the add new layer tool and selecting the Image layer option.

The georeferenced image file extensions that may be imported into GeoAgro GIS are: .PNG, .TIF, .SID, .ECW, .JP2, .BIL, .JPG and .JPEG.

To import an image or georeferenced photo into GeoAgro GIS, it must use the WGS84 geographic coordinate system (which uses latitude and longitude coordinates), as this is the coordinate system used by GeoAgro GIS.
