Creating a Tree Inventory Using ArcGIS Server and Google Streetview

March 22, 2010

The benefits of trees cannot be overstated. They provide numerous financial, health and quality of life benefits for our community. The well-being of our urban forest at the Port of San Diego is one of the key resources we manage. The PortGIS Program attempts to identify resources which are advantageous to represent spatially. By placing utilities, proposed projects, the Port Master Plan, the 2010 Tidelands Mapbook, aerial photos and our tree locations within one spatial context we empower our Port employees to make  informed decisions by driving an enterprise-wide common operating picture.  Plans for future development will account for our urban forest resources from the outset if they are included in the primary set of guiding factors. It is much more costly and less likely to occur if urban forestry management is left to expensive last-minute change orders.

Much of the Port Tidelands can be seen through Google Streetview. Some find this disconcerting and an invasion of privacy, but Google Streetview is an invaluable and (IMHO) underutilized tool for creating and managing GIS Data. It can save substantial time and monies by moving expensive field work to the desktop. Managers can easily implement quality control measures by reviewing decisions made in the field by lesser experienced personnel in real-time. Real functionality comes from combining  Google Streetview images and GIS data housed in a Relational Database Management System. This PortGIS Tree Inventory tool is a departure from our other web applications in that it empowers end users to change GIS data. Our other tools are read only.

Below is a video showing how to use this tool.

Beware- GIS Dork Out Session below

From a technical GIS/database/developer perspective, this project started out as a proof of concept. Our goal was to enable our non GIS professionals to easily create, edit and manage a discrete set of GIS data through the web. In order to do this the data needed to versioned and housed within an SDE database. We also wanted to enable security, and grant permissions through Active Directory, so only certain Port employees are able to make changes. Our goals are to continue to build on this functionality and to expand the capabilities of the PortGIS Program. We would like to take this data into the field to collect more information, i.e., standard breast height of our trees and/or take pictures of the trees using a connected handheld device. Taking the PortGIS program mobile will enable us to offer real-time GIS data management to our non-GIS professionals where and when it is most convenient. This way they can use GIS as a tool which complements their primary focus of writing leases, creating architectural renderings, fixing electrical conduits, or making our urban forest as healthy, financially viable and beautiful as possible.

A Picture is Worth a Thousand Words

So you’ve just used the PortGIS Program to figure out the distance across Harbor drive is about 66 ft, or you’ve used the streetview tool to identify the utility box which needs to be repaired. But now you want to share this information through email or in a word document. Below is a video showing an easy technique to take a screenshot and do some minor graphic design work. This is only for non-presentation quality maps. If you need a map to include in a report or presentation please contact the proper engineer, architecture  and mapping technician, or the GIS Group. I find this technique saves me time and is more accurate than trying to portray the same information in words. You can also use Snagit instead of Microsoft Paint.

Using Google Streetview within the PortGIS Explorer Web Application

May 7, 2009

We have all used Google Maps and Google Earth with amazement. Google has done an incredible job of creating engaging and easy-to-use geography visualization tools. Streetview, a feature of Google Maps and Google Earth,  provides a 360° horizontal and 290° vertical panoramic views from a row of positions along streets throughout the world. The Streetview images were collected by a camera mounted on a car or truck; therefore, the images are limited to streets. Below VS (See Docs: 315612) shows us how to use Streetview from within our PortGIS Explorer Web Application.

Data collection is the hardest part of any GIS. Google has collected an incredible amount of ground level information as geospatially referenced images. At the Port, this tool can be used to identify an unfamiliar area or be used as part of QAQC process, but the real functionality comes across when we combine Streetview images and our Port data, such as the TidelandsMapbook2007. For example, with this tool in their arsenal our Land Use Planning Department can explore areas before construction or demolition takes place. Without switching to another system, they could also research adjacent tenants, their frontage, and when their lease agreements expire.

We also wrote a blog post on how to use Streetview from within the Harbor Police Desktop Application based on ArcGIS Explorer. We want to thank ESRI, and the tool’s author, for making it available to the public through ESRI’s .Net ADF Code Gallery. See the links below to learn more about these topics
