[Geoserver-users] How to upload custom files to Geoserver

fawzyb · November 11, 2019, 7:46pm

Hi,

My environment is PostGIS + GeoServer + OpenLayers.

I need to implement a method for import/export, where the user will select some features, these features might have some custom image icons associated to them. So the features data and the images need to be exported into a single zip file.

I have no problems with the export method, I can implement a custom WPS that does all these things.

My problem is in the import method, typically in how to upload that zip file to the GeoServer.

I’ve taken a look at the Importer Plugin, but found that it can only upload vector files, which is not my case.

Could you please help me, on how to upload a custom zip file to GeoSever.

Regards,

Fawzy

Options:

as you found the importer can accept a zip file, unpack it and import the vector contents.
you may use the REST API to upload individual resources (this is intended to upload icons and fonts for example)
If you really need to upload a zip, you may wish to write a custom plugin

Where did you get this information from? The importer can import raster data too, e.g.:
https://docs.geoserver.org/latest/en/user/extensions/importer/rest_examples.html#importing-and-optimizing-a-large-image-with-a-single-request

Oh, in that case the import is the last of your problems, GeoServer has concepts only for rasters and vectors,
if your custom data can be related to one of those two (or both) you’ll have to write first a new DataStore (for the vector part)
or a new coverage reader (for the raster part).

Hard to give you more information without an explanation of what “custom” really means

Hi Andrea,

Thanks a lot for your replies.

My problem is:

1- I have a vector layer, which has some points.

2- When a user adds a point, he associates an image to it. He first needs to upload these images to GeoServer (using a custom WPS I’ve made), then assign each image to as much points as he wants.

3- Now I need to implement an Import/Export functionality in my program. So for the vector layer I decided to export it as GML, then when importing the program converts this GML to a WFS-T Insert. I’ve succeeded in that point.

4- The problem is in the images, they must be also exported, then imported to the same relative path.

5- So, I decided to export the images also and combine them with the GML file in a zip file. Then when importing I decompress the file, take the images and put them in the correct relative path, then process the GML file as described in (3).

6- My problem now is how to upload this zip file to GeoServer.

Regards,

Fawzy

Hi,
since this is a mix of info that can be directly managed by GeoServer (the GML), and info that do not (the images),
and you’re already familiar with writing a WPS process, writing another process to do the import and place the
files wherever you need would seem the easiest way.

Cheers
Andre

Hi,

The problem in this solution is that the limitation of the body of the WPS request. I tried to search if there is a limitation on that, but found that it’s just the limitation of the web-browser you are using. Is that correct? are there any other limitations on the WPS request’s body?

Fawzy

Hi,
I believe most web containers limit the size of what can be uploaded by POST, but it’s configurable… in each container in a different way.
For example, in GeoSolutions we use Tomcat, and the configuration is called maxPostSize, see here:
https://tomcat.apache.org/tomcat-8.0-doc/config/http.html

Cheers
Andrea

Hi,

I have created a custom WPS for the import stuff, and I am putting the base64 encoding of the file to be imported in the request body.

The problem now is when the file size reaches few kilo bytes (e.g. 10kb) the GeoServer throws a NullPointerException

Hi,

I believe most web containers limit the size of what can be uploaded by POST, but it’s configurable… in each container in a different way.

For example, in GeoSolutions we use Tomcat, and the configuration is called maxPostSize, see here:

https://tomcat.apache.org/tomcat-8.0-doc/config/http.html

Cheers

Hi,

The problem in this solution is that the limitation of the body of the WPS request. I tried to search if there is a limitation on that, but found that it’s just the limitation of the web-browser you are using. Is that correct? are there any other limitations on the WPS request’s body?

Hi,

since this is a mix of info that can be directly managed by GeoServer (the GML), and info that do not (the images),

and you’re already familiar with writing a WPS process, writing another process to do the import and place the

files wherever you need would seem the easiest way.

Cheers

Hi Andrea,

Thanks a lot for your replies.

My problem is:

1- I have a vector layer, which has some points.

2- When a user adds a point, he associates an image to it. He first needs to upload these images to GeoServer (using a custom WPS I’ve made), then assign each image to as much points as he wants.

3- Now I need to implement an Import/Export functionality in my program. So for the vector layer I decided to export it as GML, then when importing the program converts this GML to a WFS-T Insert. I’ve succeeded in that point.

4- The problem is in the images, they must be also exported, then imported to the same relative path.

5- So, I decided to export the images also and combine them with the GML file in a zip file. Then when importing I decompress the file, take the images and put them in the correct relative path, then process the GML file as described in (3).

6- My problem now is how to upload this zip file to GeoServer.

Regards,

Fawzy

Oh, in that case the import is the last of your problems, GeoServer has concepts only for rasters and vectors,

if your custom data can be related to one of those two (or both) you’ll have to write first a new DataStore (for the vector part)

or a new coverage reader (for the raster part).

Hard to give you more information without an explanation of what “custom” really means

Hi,

Are you running Tomcat? Try increasing the allowed request size. By default its around 100k approximately.

Hi,

Are you running Tomcat? Try increasing the allowed request size. By default its around 100k approximately.

Hi,

I believe most web containers limit the size of what can be uploaded by POST, but it’s configurable… in each container in a different way.

For example, in GeoSolutions we use Tomcat, and the configuration is called maxPostSize, see here:

https://tomcat.apache.org/tomcat-8.0-doc/config/http.html

Cheers

Hi,

The problem in this solution is that the limitation of the body of the WPS request. I tried to search if there is a limitation on that, but found that it’s just the limitation of the web-browser you are using. Is that correct? are there any other limitations on the WPS request’s body?

Fawzy

Hi,

since this is a mix of info that can be directly managed by GeoServer (the GML), and info that do not (the images),

and you’re already familiar with writing a WPS process, writing another process to do the import and place the

files wherever you need would seem the easiest way.

Cheers

Andre

Hi Andrea,

Thanks a lot for your replies.

My problem is:

1- I have a vector layer, which has some points.

2- When a user adds a point, he associates an image to it. He first needs to upload these images to GeoServer (using a custom WPS I’ve made), then assign each image to as much points as he wants.

3- Now I need to implement an Import/Export functionality in my program. So for the vector layer I decided to export it as GML, then when importing the program converts this GML to a WFS-T Insert. I’ve succeeded in that point.

4- The problem is in the images, they must be also exported, then imported to the same relative path.

5- So, I decided to export the images also and combine them with the GML file in a zip file. Then when importing I decompress the file, take the images and put them in the correct relative path, then process the GML file as described in (3).

6- My problem now is how to upload this zip file to GeoServer.

Regards,

Fawzy

My data is neither a vector nor a raster data. It’s a custom data.

Oh, in that case the import is the last of your problems, GeoServer has concepts only for rasters and vectors,

if your custom data can be related to one of those two (or both) you’ll have to write first a new DataStore (for the vector part)

or a new coverage reader (for the raster part).

Hard to give you more information without an explanation of what “custom” really means

Hi,

I believe most web containers limit the size of what can be uploaded by POST, but it’s configurable… in each container in a different way.

For example, in GeoSolutions we use Tomcat, and the configuration is called maxPostSize, see here:

https://tomcat.apache.org/tomcat-8.0-doc/config/http.html

Cheers

Hi,

The problem in this solution is that the limitation of the body of the WPS request. I tried to search if there is a limitation on that, but found that it’s just the limitation of the web-browser you are using. Is that correct? are there any other limitations on the WPS request’s body?

Regards,

Fawzy

Hi,

since this is a mix of info that can be directly managed by GeoServer (the GML), and info that do not (the images),

and you’re already familiar with writing a WPS process, writing another process to do the import and place the

files wherever you need would seem the easiest way.

Cheers

Hi Andrea,

Thanks a lot for your replies.

My problem is:

1- I have a vector layer, which has some points.

2- When a user adds a point, he associates an image to it. He first needs to upload these images to GeoServer (using a custom WPS I’ve made), then assign each image to as much points as he wants.

3- Now I need to implement an Import/Export functionality in my program. So for the vector layer I decided to export it as GML, then when importing the program converts this GML to a WFS-T Insert. I’ve succeeded in that point.

4- The problem is in the images, they must be also exported, then imported to the same relative path.

5- So, I decided to export the images also and combine them with the GML file in a zip file. Then when importing I decompress the file, take the images and put them in the correct relative path, then process the GML file as described in (3).

6- My problem now is how to upload this zip file to GeoServer.

Regards,

Fawzy

My data is neither a vector nor a raster data. It’s a custom data.

Oh, in that case the import is the last of your problems, GeoServer has concepts only for rasters and vectors,

if your custom data can be related to one of those two (or both) you’ll have to write first a new DataStore (for the vector part)

or a new coverage reader (for the raster part).

Hard to give you more information without an explanation of what “custom” really means

Cheers
