In this month’s edition of our ongoing Map Mavin Methods series, we’ll take a look at how Map Mavin can be used not just to store, view and share vector data such as shapefiles and KMLs in the cloud but also raster data in the form of GeoTIFFs. Often times you may only need to work with imagery for a particular project, and whether your needs require one or several images, Map Mavin has simplified the process of sharing and viewing such data using the cloud.
The process of uploading imagery is just as easy as any format and in fact the exact same! First, login to your Map Mavin account at www.mapmavin.com. Once logged in, you’ll see a series of tabs on the left side of your screen that will route you to their respective sections of Map Mavin. Click the My Data Layers & Folders tab and you’ll be taken to the file system holding all uploaded layers in your account. Click the Upload Layer button and you’ll be giving the opportunity to upload your .TIFF files into the system. Note: Some browsers do not have a progress bar indicating the download is in progress. Please be sure to wait a reasonable amount of time in relation to your file size (for example, files over 1 GB often take between 5-10 minutes to load into Map Mavin on a T1 connection).
Once your satellite and/or aerial images have been uploaded, a useful tool to keep in mind is our opacity bar. Go to the layer of your choice in the My Data Layers & Folders and click the General icon next to the file’s name (the General icon looks like a circular gear). You’ll see a sliding bar titled Opacity and are given the option to adjust it per layer. This allows for layers to overlay within a map project but not to obscure each other.
If you wish to download your imagery, simply click the Download icon next to the file’s name. To share the imagery with others, place it into a map project, then go to My Web Maps and click the Share icon (which appears as three figures standing in a group) to be provided with multiple ways of sharing our data.
