How to change the shape of a Line or Area Feature

A number of our iOS apps provide the Move Node function. A couple apps also provide the Insert Node function.

When you use Move Node to move a node of a Line or Area Feature, the shape will be changed. Beware, though, that there is not an undo function for Move Node. If you change your mind, you will need to manually move the node back to its original position or as close to it as possible.

The Insert Node function provides additional flexibility to change the shape of the Line or Area Feature. You can add additional nodes between two existing nodes and move the nodes to approximate the desired shape.

Edit Points, Lines and Areas within the GPS/GIS app

An important function to look for in a GPS/GIS application program is the ability to edit a Feature that has been previously recorded to correct an error or to change or add attribute information. Many of our iOS apps provide this capability.

A number of our apps provide the Move Node function. You could use it to move a Point Feature or to move a node of a Line/Area Feature.

Some of our apps provide the Delete Node and Insert Node functions, allowing you to better modify the shape of a Line or Area Feature.

In apps that provide a Sheet View, you can modify the displayed values for the Feature Attributes.

As for the coordinates of a point or node, you could change them via the Feature Properties screen.  iGPSGIS II, iCMTGIS-II, iCMTGIS III, iCMTGIS PRO, Forester GPS GIS III, Farming GPS GIS III and Utility Data Collection app will also let you use GPS to re-log the position of a Point Feature. To do so, first select that Point Feature then call up the Feature Properties screen. Then tap the “Update” button, specify the session time for collecting the data then tap the “Start” button.

Of course, if you no longer need a certain Feature, you could simply delete it.

Farming GPS GIS III for iPad released

Farming GPS GIS III provides the functionality of the Farming GPS GIS II app plus a number of new functions. Most of these new functions were ported over from the PC-GIS PRO office software.

1. Additional data import and export formats

You will also be able to import and export data in Excel and KML formats.
Point Features can be imported and exported via a text file.

2. Contour / Volume

You will be able to create a contour map based on elevation or an attribute.
The contour information will enable you to compute volumes.

3. Load GeoTiff image

You will be able to load a Geotiff image for use as background map.
Such a background map does not require wi-fi connection.
The .tif map image can be used in the Moving Map mode for data collection.

4. Classify

You will be able to classify the Features and place them on sub-layers.

5. Insert or delete nodes

Now you will be able to modify the shape of a Line or Area Feature.
by deleting some nodes or adding some nodes then moving the nodes.

6. Go to and Sort

Jump to a Feature record by specifying the search criterion.
You will also be able to sort the Features based on an Attribute.

7. Report statistics

You will be able to view the statistics for a numeric Attribute of a Feature.

8. Batch delete by text file
You will be able to delete specific Feature records based on a text file.

9. Disconnect Feature

You will be able to easily disconnect Line or Area Feature into Points.
You will be able to disconnect a Line or an Area Feature into Lines.
You will be able to disconnect an Area Feature into two sub-areas.

10. Join Features

You will be able to join Points into a Line or Area Feature.
You will be able join two Lines together to form a new Line.
You will also be able join two Areas together to form a new Area.
(This function replaces the Combine function of Farming GPS GIS II).
