The Help of the Mobile GIS Technology
A mobile GIS is a GIS system on your mobile devices, which can be very helpful for field works. For example, you can bring the mobile GIS to the fields to collect field data, and then synchronize them back to your server so that the field data can be displayed in real-time. In this article, we are going to introduce one of our mobile GIS solutions-SuperPad, to see how it works with other SuperGIS products to help the field tasks, including SuperGIS Server and SuperGIS Desktop. The figure bellows illustrates how the 3 products work together. You can use SuperGIS Desktop to prepare the necessary data, and use SuperGIS Server to upload the data so that we can download them to SuperPad for the field works. After the data are collect, we can synchronize them back to the server.
Before doing the field works, the necessary data should be prepared at first. You can use the toolkit in the SuperGIS Desktop to create the needed layers. And the feature symbols can also be designed first so that the map readers can easily understand the meaning of each feature. After the data are ready, you can publish them to SuperGIS Server as a feature service, which is an editable service, so that you can add, delete, and edit the features using SuperPad.
During the field work, you have to first download the data from the SuperGIS Server to SuperPad using the DataServiceTool extension. In addition, you can also add the OpenStreetMap as a base map using the OnlineMapTool extension.
After the data are downloaded, you can start collecting field data using the various tools provided by the SuperPad, including select tool, edit tools, GPS tools, and advanced attribute editing tools. Please note that before editing, you should enable editing and select the editable layers in the layer manager.
The select tool allows you to select an existing feature to move, edit, or delete it. You can edit the shape and the attribute value of the selected feature.
The edit tools allow you to add new features by drawing. You can draw points, lines, and polygons by using the provided tools, such as the freehand line and freehand polygon. After a new feature is added, you will need to input its attribute value.
The GPS tools allow you to add new features using GPS signals. You can add points, lines, and polygons by using the provided tools. After a new feature is added, you will need to input its attribute value.
Advanced attribute editing tool
Whenever a new feature is added, you have to input its attribute value. And this can be very troublesome, especially during the field works. The advanced attribute editing tool helps you to input the feature attribute value by selecting it from a built menu.
After the data are collected, you have to synchronize them back to the server so that the field data can be displayed in real-time, whether the users are using SuperGIS Desktop or any web browsers, as shown in the figure below.
To synchronize the data, you can use the DataServiceTool extension, and select “Synchronize data with SuperGIS Server”. Then you will see the field data in the SuperGIS Desktop and web browsers in no time!
In this article, we introduced how to use not only the SuperPad but also the SuperGIS Server and Desktop to help increase the efficiency of the field works. With SuperGIS products, you can always get your GIS works done quickly and easily!
