Geotag adds geographic information to images, video files, etc, allowing theirs positioning.

Photography cameras with GPS and Smartphones include such spatial information automatically to the EXIF metadata. EXIF data are included inside the image. It is possible to read this information right clicking the image and then selecting the tab “Summary”.

The tool “Geotagged photos to points” generates an entity class expressed in GPS coordinates, appearing 3 fields in its attributes table:

• The access route to the photo

• The name of the photo

• The date / time field that registers date and time in text format. It is possible to transform it to a date/time format with the tool “Convert the time field” which can correlate time data.

To do so, we must save all geolocated photos in a folder and follow the steps suggested by the tool.

Through a logic query it evaluates the cells of a raster generating an output raster. Those cells that meet the specified attributes return the original input value for the cell location, maintaining its format (integer or floating). Those that don’t meet these criteria, acquire a “NoData” value.

Only the elements “value” and “count” are maintained in the output raster. If any other item is specified in the query, the original value of the input is returned in the output raster.

If the input is a multiband raster, the specification will be applied to each of those bands obtaining therefore a raster multiband as the output.

To package means to create a compressed file where the map document (*.mxd), the data to which it refers and the assigned characteristics (symbology, tagging, field properties, 3D properties,..) are included.

It is possible to create these `packages´ in ArcMap, ArcScene and ArcGlobe.

The map packages (*.mpk) allow exporting maps to other PCs. It is important take into account if some of the included data are compatible with previous ArcGIS versions on the new PC. Those incompatible won’t be able to open.

To open this package tool:

File > Share as > Map package

In the dialog box we select the following:

Finally, choose the Share button and the compressed file will be created.

To do so, we are going to load a vector layer with the towns located in the region Axarquia of Malaga, Spain.

Using the “Extract by Mask” tool we indicate the input raster, the raster or entity later that we use to define the areas to extract (Input raster or feature mask data) and the name and location of the output raster.

The result would be a DEM of the Axarquia region with the imposed layer of the towns that comprise it.
