18 GIS Feature Collection with ESRI s ArcGIS Online Collector App Quick and efficient GIS Feature Inspections Replaces Paper Forms

19 Why should we use GIS? Database structure for reliable record keeping Applications that will assist in the collection, reporting, and maintenance of data

20 ArcGIS Online + Collector App Adopted in early 2014 at the City of San Marcos, ArcGIS Online is a robust platform to serve GIS data to field users without requiring a direct connection to the city s network. The Collector App is a tool that makes field collection quick and efficient. A major benefit is that it fully integrates current GIS data, and all of the collected information can be brought back into the GIS environment with little to no modifications. ArcGIS Online (AGOL) requires a username and password that is set up by an AGOL account administrator, so the data is secure. AGOL is accessible from any browser, and has many tools/gis operations that can be performed. In some cases, this can replace the need for a full ESRI license.

21 GIS Feature Inspection The Stormwater feature inspection map is a web and mobile based map that allows collection of features and attributes that do not require a high accuracy position. It is also useful in updating feature attributes that have been collected by a high accuracy survey-grade GPS device.

22 GIS Feature Inspection Features from the city s GIS system are uploaded to a webmap using the ArcGIS online platform. The features are interactive - they can be clicked on to see attributes such as pipe length, pipe depth, diameter, and other attributes that are entered in GIS.

23 GIS Feature Inspection The field crews that will inspect the GIS features will use the map to confirm that the GIS is correct, and then open up the Inspection form to complete the inspection. If necessary, the crew will document the condition with a picture. The Inspection will be created as a new point, and to connect the inspection to the GIS feature, the field crew will copy the name of the feature and insert it into the inspection form.

24 GIS Feature Inspection Some inspection items include: The Unique ID of each feature The Structural Condition (Good, Fair, Poor) If Repair or Cleaning is required The date the inspection was performed Misc. comments If errors exist in the stormwater features in the GIS data Pictures

25 GIS Feature Inspection After the inspection is complete, the pictures will show as an attachment at the bottom of the form. The picture can be opened in the app on the ipad or in a browser.

27 GIS Feature Inspection Back in the office, the data can be filtered to make only the desired records visible. Here we see only features that require maintenance.

28 GIS Feature Inspection Alternatively, you can change the symbols to represent the different attributes. Here, we include all of the inspections, but make the features that require cleaning red.

29 Replacing Paper Forms with Collector With traditional data collection, paper inspection forms would be sent out with the field crew. These forms are normally bulky (8.5x11 or larger) and would be accompanied by a clipboard, pens, and other supporting tools. Once the data was recorded, it might be days or weeks before the data could be digitized. Weather, penmanship, and other factors can affect legibility of the data. With a GIS-based collection method, the data is already in a digital format, and can be made available immediately to GIS staff and Management through internet connectivity. Further data entry errors can be mitigated with the use of drop-down lists (domains) and range values.

30 Example: Outfall Reconnaissance Inventory The collection form was based off of the MS4 Outfall Reconnaissance Inventory (ORI) sheet. A digital version can be found here:

31 ArcGIS Online: Mobile (tablets, phones) Web Maps from the browser can be published in many formats to enhance the end user s experience. The Collector app (available through the Apple app store or Google Play [Android]) allows field crews to record attribute data, location, and pictures of physical assets.

32 ArcGIS Online / Collector: Devices ArcGIS Maps can be used in the field on mobile devices for enhanced access to data The Collector app is also set up for Offline data (no need for internet access) so field crews can see infrastructure data, even if there is an internet outage or if they are in an area of poor cellular coverage. The GIS team has purchased well equipped yet reasonably priced Android devices (Samsung Galaxy Tab 4s, Lenovo Tab 2 A8s) for field collection through the Collector app. Android devices are well built and are normally much cheaper than an Apple device, which has allowed the department to purchase more devices. Performance: The Drainage crew has collected 2172 inspection points since August of 2014, and the Traffic team has collected 2250 traffic signs to aid in the detailed inventory of the city s signs. IT GIS has created a Hydrant Inspection app for the Fire Department, and the Firefighters have completed nearly 1400 inspections. These apps will help to improve the quality of our GIS data, as well as bring the departments the data they need in a reliable, instantly-available format.

43 Goals for the Future: Common Operating Picture

44 What do we do with all this data? Plan for CIP projects Update FEMA map Update ordinances Guide new development Use for the CDBG-DR Action Plan - $25 million HUD funds

45 Federal Register Requirements 70% Rule: 70% of funds MUST serve Low, Moderate Income (LMI) populations BFE Rule: ANY Substantially or Severely Damaged unit receiving CDBG-DR funds MUST be elevated to 2 Feet OVER the Base Flood Elevation when all construction is complete Disaster Rule: Use of funds for any project MUST be attributable to both 2015 floods
