Offline Mobile Map Basics: Editing Map Layers Offline

Monday, September 5th, 2016


In our second article in this series: Offline Mobile Map Basics: Offline Base-Maps and Layers, we discussed how to take base-maps and layers offline. From Esri-land Tile Packages (TPK) and Feature Layers were key discussion areas. In this third post in the series we will dig a little deeper and focus on offline mobile map editing.

Editing Map Layers Offline

As we have discussed in the previous two posts, base-maps are static. That means they are simply images or tiles stitched together to provide context. Layers are what sit on-top of base-maps and if the are Feature Layers they can be edited. What do we mean by edited? There are three types of editing:

1. Add – Imagine you are working in the pipeline industry, and are viewing on your iPad the current pipe network in an ArcGIS map app. You are currently extending the pipeline; adding an additional line. You will need to update the pipeline layer to include this new section of pipe. That means adding a new line feature.

2. Edit – You are out inspecting a power pole. When you tap the point feature which represents the pole in you mobile map app a list of attributes appears, these describe the pole; type, last inspection date etc. You notice the pole is listed as metal when you can see it is actually wood. You need to edit this features ‘material type’ attribute so it is accurate.
