How to Set Up a Data Alert – The Up-to-Date Imagery Notification Service

And this video walks you through the steps to set up a Data Alert on Image Hunter. Data Alert lets you define an area of interest anywhere around the globe, the resolution your project requires and the number of months we should keep the alert active. Once this is set up, we check for new data over your area of interest every single day, and send you an email alert when we find coverage that meets your specifications.

Tool Tips

If you would prefer written Image Hunter directions, please see below. With the recent changes to the Image Hunter user interface, a few buttons are missing directions. If you still have questions about using our online imagery search engine, please feel free to reach out to us by phone or email.

Header & Map Buttons

Pan – allows you to move the map north, south, east and west.

Zoom In/Out – allows you define a smaller (zoom in) or larger (zoom out) geographic region for your map.

Gazetteer – type in location name (i.e. city, county, address, etc.) and the map will zoom here, placing a blue marker in the correct place. Then, you will still need to define your area of interest with the coordinate entry, selection tools or by polygon upload.

Upload Polygon – select a pre-made polygon shapefile or Google Earth KMZ. All files must contain a single polygon.

Save Polygon – save your area of interest as either a polygon shapefile or Google Earth KMZ.

Coordinate Entry – define your area of interest with latitude and longitude (in either decimal degrees or degrees minutes seconds format) coordinates of the center point, corners or polygon vertices.

Rectangle Selection – click and drag on the map to create a rectangular area of interest.

Polygon Selection – allows you to create an irregular polygon by clicking on the map at each of your polygon’s vertices and then double-clicking to close the shape.

Edit Polygon – lets you manipulate an existing polygon by adding, deleting or re-positioning vertices as well as shifting the entire area of interest.

Catalog ID Search – find single or multiple images in our archive with their catalog IDs.

Measurement Tool – allows you to measure distance (displayed in kilometers, km) of a straight line or continuous segments.

Data Alert – set up an automated alert that tells you when images are collected over your area of interest.

Save Search – creates a URL plus ID that you can save or share with others to return to your exact same search results.

Settings – access to a set of additional tools to improve your Image Hunter experience: change area of interest color; move image previews up and down; and report a bug.

Basemap Layers – click this tool to change the map in the background, options include roads, terrain or imagery.

Search Result Filters

Resolution Filter – allows you to filter search results by the imagery’s resolution.

Off-Nadir Filter – allows you to filter search results by the off-nadir angle of imagery collection. The higher the off-nadir, the more tilted the satellite was when collecting imagery.

Satellite Filter – allows you to filter imagery search results for a specific satellite or set of satellites.

Cloud Cover Filter – allows you to filter imagery search results by the cloud cover percentage of the entire scene.

Date/Seasonal Filter – allows you to filter imagery search results by a continuous date range or by a seasonal date range.

Search Results & Order Submission

Search Results – your imagery search results will appear in this collapsible menu. You can sort search results by satellite, date of collection, resolution, percent cloud cover and off-nadir collection angle.

Info – this displays key collection metadata and a low resolution preview of the entire scene.

Arrows – they allow you to move an image up or down when viewing multiple scenes over an area of interest.

Review/Save – allows you to review and submit the scenes you have selected for a quotation. Also allows you to download the area of interest and selected scene footprints as a polygon shapefile or Google Earth KMZ.

Submit for Quote – this  interface submits the scenes you selected to Apollo Mapping for a price quote. You will be asked to fill in your name, email address, phone number, company and comments.
