QUESTION
I have two point on a map, one red, one blue. On this map is also a grey area.
Of my two point, I would like to display only the blue one, which inside the area.
To sum things up, I would like to filter the geometry of a layer (point) by the geometry of another layer (area)
what is the proper way to do this, with intersect?
Here is a working example :
...ANSWER
Answered 2022-Mar-09 at 15:26If you have a single polygon or multipolygon feature you could use the intersectsCoordinate
method to test if the geometry contains the point coordinate when styling the point.

I am using the Mapfish Geoserver plugin for printing maps from Geoserver. It was working just fine.
For security reasons, I added an authentication plugin that needs an "authkey" parameter to access the layers. The problem is that I am not able to pass the parameters while printing the pdf. And I could not find any alternative method.
The example URL of the WFS layer with "authkey" is:

QUESTION
I have been working on a project using Azure Indoor Maps. I started to use the Azure Maps Web SDK. I have looked for a way to loop to all features that are loaded automatically by the SDK, without making a request to WFS API https://docs.microsoft.com/en-us/rest/api/maps/v2/wfs/get-feature.
As I see the map loaded, I think that this information should be accessible directly by SDK, and I do not need to create another request. But maybe I am wrong.
I have found a method that does something similar to what I need getRenderedShapes but it only returns the features that are visible when the method is called, and I need all the features in the indoor map or in one floor.
Does anybody know if this is possible? On one side I think should be something similar to getRenderedShapes, but on the other side, I think that the front-end only has the visual information and that azure indoor maps use the Vector tile source and are optimized in the back-end and only serve to the front-end the required information.
https://docs.microsoft.com/en-us/azure/azure-maps/web-sdk-best-practices#optimize-data-sources
...The Web SDK has two data sources,
GeoJSON source: Known as the DataSource class, manages raw location data in GeoJSON format locally. Good for small to medium data sets (upwards of hundreds of thousands of features). Vector tile source: Known at the VectorTileSource class, loads data formatted as vector tiles for the current map view, based on the maps tiling system. Ideal for large to massive data sets (millions or billions of features).
Vector tile source: Known at the VectorTileSource class, loads data formatted as vector tiles for the current map view, based on the maps tiling system. Ideal for large to massive data sets (millions or billions of features).
ANSWER
Answered 2021-Sep-24 at 20:07As you noted, the map SDK only loads the indoor maps via vector tiles which are condensed set of the data set clipped to areas of the view port. This only loads a small subset of the data. This makes it possible to create a large scalable indoor map platform that in theory could support every building in the world in real time. As you noted, the getRenderedShapes function can retrieve data from the vector tiles, but only those that are in the current viewport (plus a small buffer). I believe the only way to get the data as GeoJSON if via the WFS GetFeatures service: https://docs.microsoft.com/en-us/rest/api/maps/v2/wfs/get-features
QUESTION
we are having a problem with webadapter page caches being filled up with different entries generated by URLs which contain gclid parameter which is unique for each URL.
The example of such URL is https://www.a1.hr/INTERSHOP/web/WFS/A1-Shop-Site/hr_HR/-/HRK/ViewStandardCatalog-Browse?campaignID=ljeto&gclid=EAIaIQobChMIiu7U2PGU8gIV2IeyCh311wBOEAEYASAAEgKQW_D_BwE&CatalogID=MobilePhones&CategoryName=MobilePhones
How can we tell page cache to ignore gclid parameter and to cache result for URL without glcid, so that cache key is for example: https://www.a1.hr/INTERSHOP/web/WFS/A1-Shop-Site/hr_HR/-/HRK/ViewStandardCatalog-Browse?campaignID=ljeto&CatalogID=MobilePhones&CategoryName=MobilePhones

QUESTION
I am quite unfamiliar to complex SQL requests ...
What I am trying to achieve is to display of map of active weather alerts on a leaflet map page.
Started by filling a Postgis table with the RSS feed from national weather agencies, then create a view by selecting the ROWs with an expired date later than the actual date and publishing this view through a Geoserver WFS service.
Looked nice except that each geographic area add multiple event-effective-expires features leading to a sort of multiple layers wher only the top event was displayed.
The issue I have is that for each area/polygon I have multiples lines for miscellaneous events/dates that I have to sort out.
The initial table as a structure like :

QUESTION
I want to select and zoom on the map with multiple dropdown menus. I think I'm getting .getgeometry error on my second update because of CQL_FILTER to my URL. When I make the first selection, the selected features zoom in. Whichever of the second option I tick, I get an error.
const extentyol = yollar.getFeatures().getArray()[selectyol] .getGeometry().getExtent();
I get error in this part but it works fine in first part..
I don't understand where I am doing wrong. Where is my mistake?
...ANSWER
Answered 2021-Jul-28 at 16:11I found a solution, I don't know why, but when using cql_filter, it is necessary to define the index of the object to run the '.getGeometry()' function. The '.getGeometry' function with Objectid does not work. I also did not recognize the index of the selected object as a variable, my problem was solved.
QUESTION
I have some problems with extents. I use Openlayers and a Mapserver WFS layer, with geojson as output format. I need to get my features ordered in my geojson, so I set useSpatialIndex=false in the source vector.
But the problem is that I want to fit zoom with the size of the map, for different screen sizes. So, is there a way to adjust zoom to layer extent without the function getExtent ?
...ANSWER
Answered 2021-Apr-08 at 19:14You can calculate it by iterating through the features

Answered 2021-Mar-05 at 22:09As @Mike indicated in his comment: "The image option in ol.style.Style is used to style point features with an icon or regular shapes such as a circle. Your buffered geometry is a polygon, and is styled by stroke and fill options of ol.style.Style"
