Have you ever needed to create multiple indexes for either a feature class or mosaic dataset? The Add Indexes script tools help you speed up that process by automatically creating indexes for the fields you select. The Add Feature Class Indexes script tool adds attribute indexes to an existing feature class or overwrites its existing indexes. The Add Mosaic Dataset Indexes script tool adds attribute indexes to an existing mosaic dataset or overwrites its existing indexes. Continue reading →

Have you ever needed to create rectangular features that are defined by their geographic extent? This script tool can help you speed up that process by automatically creating the polygon features using an input file with the north, south, east, and west extents. The Create Envelopes script tool was developed to create polygon features for the mapped areas of scanned map images—we call these features envelopes. While this tool was developed for a particular workflow, it can be used to create any set of regular polygon features if the bounds of the polygons are known.
By Kyle Bauer, Learn ArcGIS Team, and Craig McCabe, Subject Matter Expert In March 2014, a massive landslide wiped out a rural community near Oso, Washington. The landslide dramatically altered the landscape, destroying homes and highways. A total of 43 … Continue reading →

A new version of the ArcGIS Metadata Toolkit is now available for download. This version of the Toolkit documents how to create and share custom metadata styles that use the validation capabilities provided in the ArcGIS metadata editor with ArcGIS 10.1 SP1 for Desktop.
Customizations that change how you view and export metadata, validate metadata using an XML schema, and reduce the number of pages available in the ArcGIS metadata editor require no programming. However, the Toolkit also provides the complete source code for the metadata editor’s pages if you want to change how they work. The documentation walks you through the process of creating a custom page and adding it into the ArcGIS metadata editor, modifying the contents of a drop-down list, and changing the validation rules associated with pages in the ArcGIS metadata editor.
The ArcGIS Full Motion Video Add-In has been updated to include two sample video clips with MISB 0104.5 metadata and two brief tutorial exercises. The 10.0 and 10.1 versions have each been updated. The exercises walk you through the process … Continue reading →
In my previous blog, I discussed how Data Reviewer’s Metadata check can be configured to validate object metadata based on a formally published metadata standard such as the Federal Geographic Data Committee’s (FGDC) Content Standard for Digital Geospatial Metadata (CSDGM) or the ISO-19115/19139 international metadata standard. In the second part of the metadata series, I’d like to discuss how the Metadata check can be configured to validate metadata content based on an organization’s unique content guidelines.
The need for validating metadata element content
For many organizations, simply validating their metadata against a standard is not always enough to ensure that data publishing requirements are met. These data publishing requirements will vary based on the organization, intended use and audience of the data being documented, and may change through time as new requirements are identified. Validating metadata is particularly important for content that are defined as “free text” by a given metadata standard. Free text-based elements cannot be validated in the same way as numbers, dates or other elements which have a defined list of valid values. Free-text elements, see screenshot below, are common throughout each standard and include such things as a dataset’s title, abstract, point of contact name, contact address, etc.
For this blog topic, I’d like to talk about how ArcGIS Data Reviewer can be used to validate item metadata created to serve as documentation for an organization’s spatial data holdings. For purposes of this discussion, metadata is defined as information that describes the content, quality, condition, origin, and other characteristics of data or other pieces of information. For ArcGIS for Desktop users, this information has traditionally been authored using ArcGIS metadata editor and is typically based on either national or international metadata standards.
With the release of Data Reviewer 10, a new check for automating quality control review of item metadata was introduced. The Metadata check enables validation of metadata associated with spatial data stored in multiple formats and based on formal metadata standards. This includes validating metadata created to document objects stored in your Geodatabase (feature classes, tables, feature datasets, etc.), features stored in a shapefile, or metadata stored in stand-alone XML documents.
