ArcGIS Viewer for Flex Application Builder version 2.5.1 and some recent Adobe whitepaper resources

We’re pleased to announce the latest release of the ArcGIS Viewer for Flex Application Builder. This is a quick-turnaround maintenance release based on the 2.5 release of the ArcGIS API and Viewer for Flex. Highlights include:

  • Localization support in nine languages: Brazilian Portuguese, Chinese, English, French, German, Italian, Japanese, Russian, and Spanish. Based on your locale, the application builder and all apps created with it use one of these nine languages. The default is English.
  • Smart URL form specification for specifying ArcGIS Server REST endpoints. When adding services, you now only need to type in the server name, not the full URL. The application builder also remembers the last 50 URLs you’ve entered, and contains better error handling and messages in this area.
  • Warnings for server instances that do not have crossdomain.xml files
  • Continue reading

Web-based Automated Well Permitting

A common task for agencies managing water resources is to assess how new groundwater wells will affect groundwater availability, groundwater flow, and the effect on streamflow in sensitive areas. In many cases, agencies make use of groundwater simulation models to assess these impacts.

In a previous post we described a workflow where MODFLOW models are used to estimate the effects (either the change in water levels, drawdown, or flow) of new wells or increasing pumpage in existing wells. The workflow is based on MODFLOW Analyst tools to import, edit, and run MODFLOW models and visualize the simulated results. Because the tools are developed as Geoprocessing tools we can create different workflows that combine MODFLOW Analyst tools with the standard ArcGIS tools, scripts, and other 3rd party tools.

In addition, the Geoprocessing tools can be executed on ArcGIS Server. The advantage of creating a web-based application is that you do not need to have MODFLOW or ArcGIS installed on your computer to perform an analysis and create a map. In fact, anyone with a Web browser can run the model and analyze the results. Continue reading

Do I need to calculate statistics on a mosaic dataset after a raster function is applied?

Calculating statistics are not always required after you apply a function.  However, there are times when it may be helpful or even required.

When are statistics required?
Color correction requires up-to-date statistics.  Therefore if any functions have been applied to your mosaic dataset, since statistics were last calculated, you will need to calculate them again.

When are statistics a good idea?
Often times when you apply a function, it can change the (virtual) pixel values. If you want to keep your mosaic dataset using the most accurate statistics and rendering, then you will need to calculate statistics again.

For instance, when you use the Stretch function to map your 8-bit data to a 16-bit pixel depth, your images will probably show up black, unless you calculate statistics.

ArcGIS for Local Government Partner Specialty Taking Off

Esri is committed to developing a community of partners that are actively implementing and extending ArcGIS for Local Government. To do so, Esri created an ArcGIS for Local Government Partner Specialty, within the Esri Partner Network, to make collaboration with partners repeatable and successful. The specialty is designed for partners focused on the local government marketplace that want to work more closely with Esri on the development and deployment of ArcGIS for Local Government.

Partners in the ArcGIS for Local Government Partner Specialty provide one or both of the following:

  • Complementary applications that are based on the ArcGIS for Local Government solution
  • ArcGIS for Local Government implementation services

Recently, several Esri partners have applied to be part of the Partner Specialty, and we are pleased to announce that we now have a growing network of partners that can assist Esri users to install, configure, and extend ArcGIS for Local Government. In the coming days, you’ll see these approved partners highlighted on the new ArcGIS for Local Government resource center.

A Model to Filter Images for Build Pyramids and Statistics Tool

In ArcGIS 10.0, we introduced a new raster geoprocessing tool Build Pyramids and Statistics. You can use this tool to build pyramids and calculate statistics for all the raster datasets in a workspace, and even in a raster catalog or a mosaic dataset.

This tool provides a convenient solution to build multiple raster datasets in single step. However it works on all raster datasets in the workspace. Although the tool does not contain a filter option to allow you select a smaller collection of raster among all, we can design a simple model to do this.

This is what the model could look like:
gp_imagery_filter

National Geographic style basemap

By Aileen Buckley, Mapping Center Lead

NGBasemap - thumbnail

In case you missed the original announcement back in mid-December, National Geographic and Esri have collaborated on the production of a new basemap that reflects the NG cartographic design, typographic style, and map policies.

This basemap provides a visually appealing background for web mapping applications for mobile users, consumers, and educational purposes, and is also well suited as a general reference map for many GIS projects. Continue reading

Importing and Using Your Own Data in Business Analyst Whitepaper Now Available

At the end of 2011, the Business Analyst team created a blog series about importing and using your own data in Business Analyst. We received great feedback on this series and decided to make it available in a whitepaper.

We hope you’ll find this useful when bringing in external data and using it in Business Analyst.
