Converting line features from google earth KML and upload as routes into a GPS receiver using DNR GPS

In this post, we will deal with line features which are features that are made up of waypoints but with different starting and ending points. GPS receiver organize data in three forms, waypoints, routes and tracks. DNR GPS recognizes only two types of GPX files- waypoints and tracks when loading KML files from google earth. A menu function in DNR GPS that will take of that glitch nicely.

Task
Typically when trying to convert line feature KML files from google earth into GPX files in DNR GPS, the line features keep showing up as tracks during loading. Well this process will show you how it is done.

Procedure
1. Launch Google earth and create the path or line feature. Observe the red line we have created representing a street. Look in the places window on the left- omerelu.


2. Right Click on the layer > Save Place As.


3. In the Save as dialog box, save type as KML


4. Launch DNR GPS. File>Load From> File


5. Load into DNR GPS, make sure the file type is set to KML


6. The file is loaded into DNR GPS as a KML file. Note the line feature is loaded as a track (see red boxed areas).


7. Go to Edit > Convert Table To> Routes


8.  The file is converted to Routes immediately!!  Notice it is now loaded and seen as Routes.
Note the file is still in KML format


9. Go to File>Save To >File and save file as a GPX file. It can then be uploaded into the GPS receiver.


10. To upload the route. Connect the GPS receiver. Go to Route>Upload.1.      Follow the subsequent dialog boxes to name the file and watch out for the message box confirming ‘Upload Complete’.

Digitizing line features on a raster image using Arcmap 10.2

Line features are those features that have the a different starting point and endpoint.

In this post, we will show you
-  how to digitize line features on a raster image using Arcmap 10.2.
- create shape files that are linear.

hope you will start practicing too. we are waiting for your feedback and comments.

Digitizing point, line and polygon features into shape files QGIS

This is a continuation of our QGIS series. We started with Georeferencing (See previous post ‘Georeferencing a raster image using QGIS’) and today we will demonstrate how to digitize a raster image to create point, line and polygon shape files.


Watch and follow the video lessons carefully and send any questions, comments or observations through our feedback page. I must chip in that it is quite tasking to show the process of digitizing offsite, but we hope it is made as simple as possible. Sorry, we couldn’t add sound as this would make the video too heavy to embed, we are working on that technicality.


Tips

• Mouse Right Click on the Layer when you want to Open the attribute table
• Make sure the layer you are creating and the raster image have the same spatial reference. Note how the spatial reference was changed in the video – ‘Digitizing polygon features’.
• The ID field on the attribute table serves as index key to join database or tables.
• Right click when u finish tracing a feature so the table to fill will pop up.
• To delete the trace, open the attribute table, select it and use the trash bin icon to delete it.
