While preparing for a demonstration showcasing some new Geoprocessing tools, I found a way to have the outputs of a tool to use a different default symbol than what ArcMap assigns the result when added to the map.
To do this, in ArcMap, run the tool to get the result you’re looking for, then open the Symbol Selector (single click on the symbol in the TOC). Next, change the symbology for the output to whichever icon/color you’d like to use, here I created a photo icon. In the Symbol Selector window, click on Save As…
Next, name the newly created symbol with the same name as the output generated from the tool (ex, Photos).
Now, when you run a tool that outputs to that geometry type and name, it will default the symbology to what you created. The key is it must be the same name every time.
We’ve just uploaded two new gas templates.
The DIMP Risk Calculator is provided as an example of how a gas distribution utility can apply its data sources to define the risk and impact of gas system failure. The datasets defined in the model represent information from several utilities regarding factors that influence the risk of system failure. These risk factors are ranked on a scale of 0–9 and represent the utilities’ quantification of the influence exuded on a gas system’s overall risk of failure.
The “Market Potential Tool” demonstrates how Census data can be used with a Gas Utilities Customer Information System to identify areas of low Market penetration. The “Potential Customers Tool” demonstrates how commercially available data, such as Navteq’s point location database, can be used to identify specific buildings which are not active Gas utility customers, but are near existing gas system mains.

I hope you all had wonderful Holiday and a Happy New Year! 2010 is in the books and was a banner year for the Electric and Gas Resource Center since we officially went live in the end of June, just in time for the Esri International User Conference in San Diego. We released two templates at the onset and have since put up one more.
Well, today we’re releasing two more templates! For those working with ArcGIS 10 and wanting to leverage the new ArcGIS API for Flex 2.2 we’ve put together a new Operational Dashboard using ArcGIS API for Flex 2.2 and using new ArcGIS 10 capabilities including;
-Web Editing with Feature Services
-Time aware layers
For those that attended the 2010 EGUG Conference in Dearborn, MI we’ve released the Streetlight Outage Viewer we showed on the plenary stage using the ArcGIS API for Silverlight. This template demonstrates the new Feature Services at ArcGIS 10 and how you can update existing features on the web.
You can access the new templates here.
We’re always working on updating existing templates andbuilding new functionality by gathering requirements and feedback from you, the user community. So please post comments and suggestions as to what you’re looking for and what we can do better. Thanks!
Now that EGUG is over and we’ve recovered from our trip to Dearborn, MI it’s time to get back to work and fulfill the promises we made at the conference! With that, I give you the newest geoprocessing template the Preliminary Wind Project Suitability Model.
Here is some more detailed information on the geoprocessing model;
Utilities across the United States are facing mandates requiring a portion of their power generation come from renewable sources. In many areas of the country wind is prevalent; however challenges exist in mitigating impacts on the land and finding buildable sites, due to a range of factors. Sensitive areas such as wetlands, rare and endangered wildlife habitat, and conservation land may be restricted for wind development, while proximity to existing electric transmission lines and land with a certain minimum average wind speed remain highly favorable. Geographic Information Systems (GIS) and geoprocessing models can help focus efforts and reduce environmental impacts by ranking the most suitable areas while avoiding restricted or sensitive areas. Multiple data sources can be included in the analysis and be adjusted for user preferences, leading to a highly efficient and tailored process.
GIS can help with many aspects of a wind project including the initial suitability modeling as well as planning, turbine siting, permitting, outreach, land management, and operations and maintenance. For this post we wanted to focus on the first step in any new wind project, finding suitable sites. Historically, this is done by putting “boots on the ground” and conducting extensive research. This could include trips to the field to investigate properties and site characteristics, reviewing wind resource and topography maps, researching land ownership information and estimating the proximity to existing electric transmission lines. These initial site assessment efforts can be error prone, costly and time consuming. GIS can help save time by consolidating relevant data sources prior to field visits, and providing analysis tools to locate the most suitable wind development sites across the study area which could be one town or an entire region. Results can then be shared with stakeholders in a graphical format that is easy to understand. The geoprocessing model becomes a way to document the analysis that was performed.
ArcGIS geoprocessing allows you to focus on an entire region, state, or project specific area to model many key factors that may be important for siting a wind project. Data values can be ranked from low to highly favorable and can be combined into a weighted overlay. Using the weighted overlay tool you can assign a percent influence to each factor indicating the importance of that factor in determining the suitability for wind project development. These data inputs are combined using a model, resulting in a repeatable and configurable pattern. A geoprocessing model template was developed as a starting point to aid decision makers in selecting wind project sites. The model will take any number of contributing factors and produce a continuous surface showing the most favorable locations. The result easily indentifies potential sites therefore expediting the initial work and lowering planning costs. Using the attached model template, you can study your own areas of interest by loading localized datasets into the predefined data inputs, adjusting the rankings, percent influence and then reviewing your results. The template serves as an example of how you can conduct preliminary wind project suitability modeling using GIS. It is not meant to substitute further research, detailed wind resource studies, nor is it meant meant to encompass all of the constraints that may exist. An ArcGIS geoprocessing model provides a simple and flexible way to analyze complex data relationships and scenarios.
Keep on the lookout for more templates this month!
As always, let us know if you have any problems or feedback.
More exciting news for the Electric and Gas community!
Esri is happy to announce the launch of the Electric and Gas Resource Center! Here we provide you with free downloadable templates built around Esri’s ArcGIS software
One of the highlights of the Electric and Gas Resource Center is a set of templates built with core Esri technology. We’ve posted two templates for the initial launch with more to come. These templates are for maintaining operational awareness and fostering communication across your organization, and efficiently planning and analyzing risk along your network.
The goal of our templates is to give you real-world examples of how to deploy the ArcGIS product suite in your industry. In each template you’ll find a sample geodatabase, map documents, an application and the documentation to help you configure the template. Also, check out the videos that we’ve posted to give you an introduction to each component.
We would like to thank the City of Fort Pierce, Florida and St Lucie County, Florida for allowing us to include a sample of their data in our templates. Allowing us to develop these sample templates with real customer data makes the samples a more powerful example of the benefits electric and gas utilities can expect from deploying Esri technology.
Remember, the Electric and Gas Resource Center is for you, the Esri users – so we encourage your feedback on the templates we’ve provided and ask that you post comments for each template. We’ll be using your comments as a guide for changes to our templates and for new templates we’ll develop in the future. We welcome your feedback, comments and suggestions. You can either post comments to this blog or e-mail us at email@example.com.
