San Mateo County Survey Marker GIS Part 3 - Data Collection

This post will outline how the data in the Survey Marker GIS is collected.

The GIS can be found here or through our Surveying and Map Checking website.

ArcGIS Collector
When it became necessary to inventory the survey monuments in San Mateo County, many data collection methods were evaluated.  We needed it to be cost effective, easy to perform, and the ability to crowd source was also important.

This is where ArcGIS Collector came into the picture.  ArcGIS Collector is a mobile app that can turn an Android or iOS device into a GIS grade data collector.  The data collected automatically appears on a web-based GIS that anyone can browse.

The way this GIS works is pretty simple.  Once the Collector app is installed on the smartphone or tablet simply login, launch the map, collect data.

That how simple it is.  There is additional functionality to the mobile app which we'll try to cover in a video or live training session.

Detailed Data Collection Screen Shots
A collection of screen shots in this Google folder demonstrate the data collection function.  Open the "info" pane to see notes that describe each screenshot.
