How do I download files?

Once logged into the site, simply click the download link on a dataset page that says "Click here to download dataset" to initiate the download request. The size of the file is also included in the link on each item page. Metadata files for each dataset can be downloaded from the individual item pages or from the page for that overall dataset.

Where can I check on the status of my download requests?

To monitor your download requests or to access the download link, go to the "My Downloads" tab in the menu. You will also receive an email with the link when the file is ready to download.

Why did I get an email telling me to resubmit my requests?

During periods of heavy use, the system may have a delay processing a request or be unable to successfully retrieve the file. In that case, or in the case of an outage or maintenance related to the file storage system utilized, a request may fail and need to be sent again.

How do I determine which file in an archive I need?

When available, the metadata for a dataset includes a shapefile that shows the location of each tile. For most state imagery datasets, the x/y min are included in the file name (for example, in2021_04152062_06.zip has an x min of 0415 and a y min of 2062).

Where can I find more information about a dataset?

Detailed information about the data included in the ISDP can be found under Dataset Information in the main menu. There are pages for different categories of datasets (imagery, elevation, NAIP, etc.) that link to the individual page for each dataset, including contact information for the data provider when available.

Extracting ISO Images

An image is a file that copies an original piece of media, whether an ISO, floppy, or other media image. This file not only contains individual data files, but also track and sector information; it arranges all this information in a file system, just like disk media. Image files, unlike normal files, are usually not opened; rather, they are mounted.

An ISO image is a CD-ROM or DVD image saved in ISO-9660 format.

ISO images are often used as source files from which to create media: After you download an image, you can use disc-burning software to recreate the physical CD-ROM or DVD (e.g., as backup install media). Alternatively, you can mount the image to access the content within it.

The data set is in the public domain and has no restrictions on distribution. The state of Indiana asks that you create and place on any media created from this data set the appropriate CD or DVD labels. Credit should be listed as "IndianaMap Framework Data", with links to the IndianaMap. The IndianaMap logo can be used on maps and web sites with the data.

To extract the files, first locate and download the ISO file for the desired geographic location in ISDP. Next:

• Option 1: Open the iso archive using an application such as WinZIP or 7-ZIP.
• Option 2: Extract all images on the ISO file by burning a CD or DVD. Use your preferred CD-writing software, such as Nero or Roxio.
• Be sure to open the .iso file for burning to media; do not add the .iso file as data to be burned. Adding the file as data will save it to the medium as an iso file and not unpack the archive.
