WebGIS Development: Create Raster Time series animation with Geoserver and OpenLayers

[@EnricoMagazzino]

Hi, Thanks a lot for your tutorial it was very helpful! I have some troubles adding a second layer with another timeseries (LST_timeseries) and Legends with color ramps that I want to add. Can I ask you for advice? Cheers

Thanks a lot

Thank 🙇

excuse me, I have a problem like this, when i added source : Could not list layers for this store, an error occurred retrieving them: Failed to create reader from file:coverages/timeseries_data and hints Hints: EXECUTOR_SERVICE = java.util.concurrent.ThreadPoolExecutor@18b9592[Running, pool size = 0, active threads = 0, queued tasks = 0, completed tasks = 0] REPOSITORY = org.geoserver.catalog.CatalogRepository@2a9727 System defaults: LENIENT_DATUM_SHIFT = true FEATURE_FACTORY = org.geotools.feature.LenientFeatureFactoryImpl@f2e97e COMPARISON_TOLERANCE = 1.0E-8 FORCE_AXIS_ORDER_HONORING = http FILTER_FACTORY = FilterFactoryImpl FORCE_LONGITUDE_FIRST_AXIS_ORDER = true GRID_COVERAGE_FACTORY = GridCoverageFactory TILE_ENCODING = null STYLE_FACTORY = StyleFactoryImpl What is wrong ??

Most probably, your geotiff is corrupt. I faced this issue because my geotiff was in an unsupported projection. After reprojecting it to EPSG:3857, it worked.

Hello sir, can you give me opinion? i have learned GEE (library to analyzing and framework to building apps). Next, i want to learning web development, between openlayers and leaflet which is more similar to the GEE ?

[@OpenGeoLab]

Openlayers and leaflet both are javascript library GEE is available in javascript and python. So, GEE openlayers and leaflet all are javascript based, but application of GEE and openlayers/Leaflet are entirely different. 1. GEE is basically for Geospatial analysis, processing of satellite image etc. 2. Openlayers/Leaflet are front end api for developing Web application.

@@OpenGeoLab thank you so much

[@shidharthrouth]

can we still publish the layers after deleting the dependent raster files from the folder ?

[@OpenGeoLab]

I think you should be able..to....I will check..and revert Generally if you can anything in the layer.. in geoserver...it will automatically reflect..on the web client on reload

[@OpenGeoLab]

One can use the geoserve rest api for making configuration changes through client side..if you delete one of the raster after publishing....it will not show that particular raster, because in the sshapefile which has been created has a entry of that particular raster but raster I missing. If you want to update the shapefile and republish the datasets..then rest api of geoserver can be used..you can see following links for that docs.geoserver.org/stable/en/user/rest/ docs.geoserver.org/stable/en/user/rest/imagemosaic.html#updating-an-image-mosaic-contents Using rest api one create new workspace, store or publish layers from.the client without using geoserver gui

@@OpenGeoLab thank you so much for the explanation… sorry to ask you but can you do a video on how tiling in geoserver works, or at least point me to the resources that show it ?

How can we achieve the same for vector data?

[@OpenGeoLab]

Check this..link for vector data you need to have time attribute in the shapefile...docs.geoserver.geo-solutions.it/edu/en/multidim/vector/index.html

Hi , This is very helpful. Can you please share a doc or video on How to serve a basemap from S3 bucket. Now a days, people are using cloud to store data. so this could be helpful to us. Basically the question is 1. How to generate basemap using GDAL tiles Or Geowebcache 2. How to upload it to S3 3. How to serve it in WebGIS I have been trying to find such tutorial in yutube. But could not find so far. thank you

[@OpenGeoLab]

For generating your own basemaps please see this video.. kzbin.info/www/bejne/bYnOZXmleb90f9E In this video I have shown how to create your own basemap using osm stored in postgis and using tilecaching which is basically geowebcache in geoserver and how to integerate that basemap in webpage using openlayers..

[@dksivagis1]

@@OpenGeoLab Thank you So much. this is very useful. I have one question. Can i take the catche created inside Geowebcache folder to S3 and consume from there ?
