How to: the Montgomery Botanical Center App

The featured map this week on the website is the Montgomery Botanical Center champion trees application. Here’s an overview of how easy it was to create this application, which required no programming, using ArcGIS Online web maps and easy-to-configure application templates.

New Flood Planning Map will help river communities prepare for seasonal flooding

This month we released the Flood Planning Map, the first in a series of maps and apps to help emergency managers and community leaders prepare for flooding events.

The Flood Planning Map provides flood planners with a set of tools and workflows to prepare for seasonal river flooding. These tools and workflows are based on real-world examples that have been used during previous flood events in the upper Midwest. Seasonal river flood planning is typically conducted weeks or months in advance of predicted crest in each community.  This advance notice gives community leaders time to plan for securing assets, protecting infrastructure, or evacuating citizens within the impact area.

The first version of the Flood Planning Map provides the ability to do the following:

  • Determine the flood impact area based on predicted flood levels.
  • Identify critical infrastructure, facilities, and citizens that could be impacted.
  • Create budgetary cost estimates for temporary levees.
  • Share the results with others who will execute the flood plan.

The basic building blocks of ArcGIS symbols

By Aileen Buckley, Mapping Center Lead

ArcGIS Symbols - Thumbnail

In ArcGIS, symbols are used not only to draw and label geographic features, but also to display various map elements, such as legends, scale bars and north arrows. They are also used to display any graphics you may add to the map, such as bounding boxes, logos, and text.

Because they are used so extensively, you may sometimes want to create your own symbols. Before you do this, it would be helpful to understand the basic building blocks of symbols.

There are three primary building blocks—fonts, colors, and pictures. To help you gain a deeper understanding of these basic building blocks and how they are used in ArcGIS symbols, we have written a series of three blog posts, each of which is dedicated to one of the building blocks.

Including netCDF Dimension Values in the Name of an Output Layer or Table

NetCDF (network Common Data Form) is a file format for storing multidimensional scientific data (variables) such as temperature, humidity, pressure, wind speed, and direction. Each of these variables can be displayed through a dimension (such as time, date, or depth) in ArcGIS by making a layer or table view from the netCDF file.  The layer or table view represents one “slice” of the dimension (for example a single date or depth).

Developer Summit 2012 recap – Silverlight, SharePoint, Office, & Windows Phone

It was great to see all of you at this year’s Developer Summit! Hopefully you were able to come by the Islands, Meet the Teams, or attend a Technical Workshop and chat with one of us:

Silverlight team at Developer Summit 2012

We received lots of good feedback from you this year, and we are pleased to announce that v3.0 Final of the ArcGIS API for Silverlight will support development with both Silverlight 4 and Silverlight 5!

In addition to talking with you about your work and getting feedback, one of our goals every year at the Developer Summit is to provide Technical Workshops with valuable information, best practices, and samples that you can take back with you. If you attended the Developer Summit but missed any of the Silverlight/SharePoint/Windows Phone presentations, or were unable to attend and would like the info, here are a few links you may find of interest:

Pictures in ArcGIS symbols

By Aileen Buckley, Mapping Center Lead, and John Cranfill, Esri Product Engineer

Pictures - Thumbnail

There are three primary building blocks of standard symbols in ArcGIS—colors, fonts, and pictures. Previous blog entries discussed fonts and colors in ArcGIS symbols. This post discusses pictures used in marker, line, and fill symbols. It reviews the file formats that can be used for pictures and explains tiled picture fill symbols and special considerations for creating them. It also discusses what happens when you share ArcGIS documents that use pictures for symbols. Continue reading

Tips for displaying photos in pop-ups

When displaying photos or other images in ArcGIS Online web map pop-ups it’s sometimes the small things that can make a big difference in the user experience. A small project recently completed for the Montgomery Botanical Center is an example of how you can do some minor tweaks to optimize your photos in pop-ups, and put your best pop-up forward.

For this project we received the locations of trees within the Center in a spreadsheet, along with photographs of each tree. The photographs were quite large – over 5 MB each.

In our first iteration we placed the photos at a web location and added a column to our spreadsheet that included the URL to each photo so we could configure them into our pop-up. Here’s the raw pop-up after we first dragged and dropped the spreadsheet onto our map:

Using Product Library to Store Editing Business Rules

In a previous blog, A Spatially Enabled Document Management System, I provided a basic overview of Esri Production Mapping’s product library. Now, the next step is to start thinking about the ways in which you could implement product library in your organization. So first, I’d like to focus on the types of editing business rules that can be stored and managed in product library.

“Business rules” is a term we use to refer to the logic you build into Production Mapping to ensure the data and maps produced meet the specifications of your organization or industry. Some of the common types of business rules apply to data validation, symbology, attribute display, and surround elements. The behavior of many tools can be customized in Production Mapping based on how you build your business rules. For example, when editing feature attributes you can validate them against rules you pre-define using Production Mapping. This ensures that only valid data is entered into your GIS. In the following sections we will discuss the types of editing business rules that can be configured with Production Mapping and managed in product library.

Configuring ArcGIS for SharePoint to work with SSL-secured sites

The components included in ArcGIS for SharePoint – the ArcGIS Map Web Part, ArcGIS Geocoding Workflow, and ArcGIS Location Field – each reference services from ArcGIS Online out-of-the-box.  By default, they access these services over http.  But due to the cross-scheme restrictions of Silverlight, the default use of http introduces problems when ArcGIS for SharePoint is used within a SharePoint site that employs Secure Sockets Layer (SSL or https) protection.  So when loading the Map Web Part on an https site, the following prompt will be shown:Mixed content prompt
