[Geoserver-users] image mosaic custom dimension to select raster images from their footprints

GeoServer GeoServer User
1

Hello list,

Thanks in advance for your help with the following.

We have a large number of raster images and a shape file (sample attached) with polygons each representing the footprint of each raster image.

The use case would be to display the footprints on a map and give the user the ability to click on a polygon / footprint in order to display the corresponding raster image.

I would appreciate a lot your guidance regarding the approach to take in order to configure Geoserver Image mosaic to serve the above purpose. Which of the below approaches is correct?

  • Configure the indexer and regex properties files for a custom parameter, e.g. location along side the shapefile containing the footprints of the images. Do I need to configurethe footprints.properties file too?

OR

  • Define the indexer.xml

Many thanks

Ivo

Ciao Ivo,
if the ImageMosaic content changes over time it would be better to use
a real DBMS as the index, like postgis or oracle.

That said, sticking with a shapefile, I would simple add another
attribute ot it (postprocess with QGIS for exmple) with a unique
identifier for each row in the shapefile (e.g. the filename or an
UUID) and expose the shapefile also as an indipendent layer. You can
then send CQL_FILTER vendor option to the imagemosaic layer to filter
individual granules using such attribute.

As an alternative, if this an administrative gui you can use the REST
Interface for ImageMosaic that let's you access the index with WFS
like syntax over REST calls:
http://geoserver.geo-solutions.it/multidim/en/rest/index.html

Another alternative to explore would be to use FIDs to syncrhonize the
polygon layer with the mosaic layer.
Generally speaking I would not rely too much on exposing the location attribute.

Ciao Simone,

Thanks for your email.

The image mosaic content does not change, hence no need to use a DBMS at the moment, but thank you for pointing it out as the use case might change in the future.

I will add the unique identifier to the shape file as you suggested and expose the shp file as a layer within geoserver.

I assume I still need to configure the custom parameter for the image mosaic! Shall I need to do so through the properties files (if so, can you please list all the properties files I need to configure? do you have an example of indexer and regex files for the definition of the custom parameter?) or do I need to use the indexer.xml file instead?

Many thanks
Ivo

Not really, you can send filters to the imagemosaic using CQL_FILTER
vendor option or via OGC XML Filters and expect this to be applied on
portions of the underlying mosaic index.
Using an additional dimension is another way to do that but requires a
little more config.

The easiest thing at that point would be to use an indexer.properties
to parse as an instance the filename (assuming it is unique) and
putting that into a String attribute.

Shall I need to do so through the properties files (if so, can you
please list all the properties files I need to configure? do you have an

parameter?) or do I need to use the indexer.xml file instead?

Hello list,

Thanks in advance for your help with the following.

We have a large number of raster images and a shape file (sample
attached)
with polygons each representing the footprint of each raster image.

The use case would be to display the footprints on a map and give the
user
the ability to click on a polygon / footprint in order to display the
corresponding raster image.

I would appreciate a lot your guidance regarding the approach to take in
order to configure Geoserver Image mosaic to serve the above purpose.
Which
of the below approaches is correct?

Configure the indexer and regex properties files for a custom
parameter,
e.g. location along side the shapefile containing the footprints of the
images. Do I need to configurethe footprints.properties file too?

OR

Define the indexer.xml

Many thanks

Ivo
