Introducing Image Space Analysis

Oblique imagery in image space

For decades, you’ve seen imagery projected onto a 2D map in ArcGIS the same way – a way that works well for “directly above you” vertical imagery, but makes oblique imagery highly distorted and difficult for analysis. New this year … Continue reading

Custom Image Processing 2.0

python

You can now use Python to create your own raster functions in ArcGIS. Previously, this was done in the .NET framework. Python is more accessible for users and allows you to plug into any of the Python libraries, such as … Continue reading

Measuring on Imagery in ArcGIS 10.1

Imagery Analysts frequently have to measure features and determine their height.  At ArcGIS 10.1, the Image Analysis window provides tools that give you the ability to take measurements of building heights directly from imagery.  The process of making such measurements on imagery is referred to as mensuration.  Mensuration tools apply geometric rules to find the length of lines, surface areas, or volumes using information obtained from lines and angles. Mensuration can include measuring the height and absolute location of features. Any georeferenced raster dataset can provide distance, area, point, and centroid location. Height measurements can be obtained when the sensor model is known. Sun angle information is required for measurements using shadows, while 3D measurements require a DEM.

This image shows how you could use the Base to Shadow tool to find the height of a building.  The height is calculated by selecting a point at the base of the building and the corresponding point at the top of the shadow.  For more information on the Mensuration tools and how to use them, see the ArcGIS Online Help.

ArcGIS for Defense and Intelligence at the 2011 Esri International User Conference

The ArcGIS for Defense and Intelligence team will be presenting a series of five technical workshops at the 2011 Esri International User Conference, on Wednesday, 13 July 2011 in room 26A of the San Diego Convention Center.

The theme of the series comes from Letitia A. Long’s presentation at the GEOINT Symposium last November.   The title of her presentation was “Putting the Power of GEOINT in Your Hands”.   Specifically, we will discuss how to use ArcGIS to “exploit the spatial and temporal properties of data; to discover patterns, trends, signatures and correlations in the data; and to communicate the GEOINT analysis visually”.  We will show “the ability to look at a huge amount of information through a spatial and temporal lens, in an interrelated way”.   Our demonstrations will show that we can find signatures for activity and phenomena, display data on a map to reveal patterns that are not evident in textual data and in the end, make analysis more predictive.  Using information from intelligence, ArcGIS further supports developing military plans using standard military symbology.   The five technical workshops are:

  • An Introduction to ArcGIS for Defense and Intelligence #1624   Ben Conklin

    ArcGIS maps and applications help defense and intelligence communities’ members apply GIS to build plans, monitor current operations, and conduct intelligence analysis. This workshop will provide an overview of the resources available for the defense and intelligence user communities. The workshop will include demonstrations of maps and application templates designed for the defense and intelligence communities.

  • Creating Basemaps for the Defense and Intelligence Community #1625   Eric Linz and Matt Funk
    Basemaps provide a foundation for all sorts of defense and intelligence operations. In this session, the role of basemaps in defense and intelligence applications will be explored as well as describing and demonstrating how to create useful multi-resolution basemaps from mapping agency data using templates. Other topics in this session include: recommendations and best practices, using basemaps in ArcGIS Explorer, ArcMap, and mobile applications, and available resources on ArcGIS.com.

  • Using ArcGIS for Intelligence Analysis #1626   Matt Funk and Mary Clawson
    Intelligence analysts use maps to merge information from many sensors and sources to find patterns, understand the enemy, and solve complex intelligence problems. Analysts compile and share databases of derived information and use maps to present in?depth intelligence briefings. In this session, we will discuss how the geospatial approach supports intelligence analysis.  We will create, analyze, and disseminate intelligence maps through desktop and Web application templates to solve intelligence problems. Additionally, we will demonstrate how well?designed maps and workflows serve as the foundation for consistent, shareable intelligence maps.

  • Using ArcGIS for Military Planning and Operations #1627   Lorraine Funkhouser and Derek Foll
    Planners use maps to develop and communicate concepts, plans, and designs. Maps support the military decision?making process and inform the commander and staff of enemy intentions and friendly activities. Planners analyze information about the weather, enemy, and terrain in order to evaluate the effectiveness of plans or feasibility of a specific operation. We will explain how ArcGIS supports a common situation awareness.  We will demonstrate how maps are used to support planning and operations through desktop, web and mobile applications.

  • Using Imagery for Intelligence Analysis #1628   Eric Linz and Derek Foll
    Intelligence analysts use imagery from various sources to find patterns, understand the enemy, and solve complex intelligence problems. In this session, we will describe and demonstrate the capabilities of the Image Analysis window and other tools for exploiting imagery. Other topics in this session include: how imagery is stored and managed in ArcGIS, using multispectral imagery for analysis, on-the-fly processing, and available imagery resources on ArcGIS.com.

All workshops are scheduled on Wednesday, 13 July 2011 in room 26A of the San Diego Convention Center.
