5. Image Resolution

Select Image Resolution from the dropdown menu. The Image Resolution options are determined by Type of Imagery and are populated after Type of Imagery has been entered.

6. Max Cloud Cover

Select the maximum cloud cover you will accept for your project’s data needs. Restricting the Max Cloud Cover to too small percentages may delay data acquisition if the cloud conditions are not met.

7. Acquisition Start

Enter the first acquisition date that you will accept for data for your project.  If you are accepting archived imagery, put in the oldest date your will accept.

8. Acquisition End

Enter the last date you will accept collection of imagery, or the end date of archived imagery you will accept.

9. Repetitive Imaging Required?

This field allows for multiple data acquisitions. Select the frequency of requested data acquisition from the dropdown menu (No - Single Collection, Daily, Weekly, Bi-Weekly, or Monthly).

C. Request Details

Add any additional information you feel may be needed to get the data/product you need.

D.  Spatial Requirements Section

Use the following controls to navigate the map:

Zoom - click the plus sign (+) to zoom in to the center of the map; click the minus sign (–) to zoom out. The mouse scroll wheel can also be used to zoom in or out.

Pan - click and drag the map to the desired location or view.

The Spatial Tools (Figure 1) allows users to define the area of interest by using the mouse or typing in the latitude and longitude. Coordinates can be displayed and entered as Decimal Degrees or Degrees, Minutes, and Seconds (DMS).

The Geometry Type tool allows users to define the area of interest by using the mouse or typing in the latitude and longitude.

Decimal degrees coordinates that are entered manually have a valid range of ± 90.00000 for latitude and ± 180.00000 for longitude (Figure 2). Negative values are used for south and west. A longitude of 99.0762 west would be entered as -99.0762.

Sources/Usage: Public Domain. View Media Details

DMS coordinates that are entered manually need to be entered as Degree/Minute/Second/Direction with the direction indicated by N, S, E, or W (Figure 3).

Sources/Usage: Public Domain. View Media Details

Geometry Types include Point, Bounding Box, Multi-Point Polygon, Pre-defined Area (within the United States), KML Upload, or Shapefile Upload. The trash can icon  can be used at any time to clear the map. 

1.  Point

To define a geographic location using a single point, select Point  from the Geometry Type toolbar.

Click an area on the map once using the mouse to define a single point search.

The Latitude and Longitude can also be entered manually. Expand the Show Options window. Enter coordinates in decimal degrees then click on Set Point.  

2.  Bounding Box

To define a geographic location by creating a box, select Bounding Box  from the Geometry Type toolbar.

Two points are used to define a bounding box - click on the map to indicate the upper left corner and the lower right corner for the area of interest (any opposite corners will work). 

The latitude and longitude for the upper left corner and the lower right corner can also be entered manually. Expand the Show Options window. Enter coordinates for opposite corners of a box in decimal degrees then click on Set Point.

3.  Multi-Point Polygon

To define a geographic location by creating a polygon, select Multi-Point Polygon  from the Geometry Type toolbar.

Click multiple times on the map to define the area of interest. Up to 50 points can be used to create the polygon.

The Latitude and Longitude can also be entered manually. Expand the Show Options window. Enter coordinates in decimal degrees then click on Add Point. Add up to 50 points to complete the polygon.

4.  Pre-defined Area

To define a geographic location using a pre-defined boundary (within the United States), select Pre-defined Area from the Geometry Type toolbar.

A menu of states, counties, and congressional districts are available for the United States. Select the desired location from the dropdown menus.

5.  KML Upload

To define a geographic location using a KML file, select KML Upload from the Geometry Type toolbar.

Enter a Spatial Name for the area of interest. Use the Browse button to upload a Google Earth Keyhole Markup Language (KML) file. The KML file is limited to a single point or a multi-point single polygon. The uploaded KML file can be accessed through the Setting link on the top toolbar using the Spatial Name if additional data types are requested.

6.  Shapefile Upload

To define a geographic location using a shapefile, select Shapefile Upload  from the Geometry Type toolbar.

Enter a Spatial Name for the area of interest. Use the Browse button to upload the shapefile components. The shapefile dialog box requires .shp, .shx, .dbf, and .prj files for the upload. The shapefile is limited to a single point or a multi-point single polygon. The uploaded shapefile can be accessed through the Setting link on the top toolbar using the Spatial Name if additional data types are requested.

7. Clear Geometry

Click the garbage can icon to clear the geometry currently selected from any type of geometric selection.

E.  Submit Request

Select the Submit button in the lower left hand corner of the screen. A status bar appears indicating that the request was successfully submitted and is awaiting approval (pending). 

An automated email is sent to confirm the request and to provide a link to the DAR details. After leaving the CIDR site the request can be edited using the link in the email. DARs can only be edited while in pending status. The DAR can be shared with another emergency responder using the Email DAR Information link. Only one email address can be entered per transaction.

The DAR may be edited prior to approval. If additional Imagery Types are needed for the requirement, a copy of the DAR can be used as a template to create additional data requests.

The user will be able to track the status of the request and receive active notifications from the CIDR tool regarding any changes in the status of the request.

3.  Data Collection

The CIDR Administrator reviews and approves pending requests, making basics modifications if necessary

4.  Data Download or Order

Notification of new image availability is sent automatically to the requestor. When a new acquisition matches the search criteria, an email is sent to the requestor from the Standing Request module.
