QUESTION
I am using Python's Apache Sedona to open a GeoJson file. I followed this guide. I follow every step for opening a GeoJson, but for the sake of clarity, this is what I did:
...ANSWER
Answered 2022-Mar-27 at 21:03As @Paul H pointed, the issue was related to the format. This was surprising as the file was an IMDF file verified by Apple... however, the GeoJsonReader renders it as corrupt. To solve the issue, filter the geojson from the 'Features' key.

Working my way through GeoTools. Just trying to read features from a view in postgresql that is not in public schema. I have a bunch of views in a schema called cache
ANSWER
Answered 2022-Mar-01 at 08:25You don't show the code setting your map of parameters, but I suspect you didn't include a schema key so the database connection defaults to public. You need a line like:

I have built a tiny web app in Vaadin 8 and migrated to Vaadin 14 MPR. The components are displaying but during the jetty:run I get exception as below
[qtp729679840-28] INFO com.vaadin.flow.router.RouteNotFoundError - Couldn't find route for 'sw.js' com.vaadin.flow.router.NotFoundException: Couldn't find route for 'sw.js'
I have added the dependencies as shown in the pom.xml. I am trying to add one or more components to a Vaadin 8 designer file, which had only two vertical layouts.
pom.xml
...ANSWER
Answered 2022-Jan-05 at 07:59I got an answer from Vaadin Team. I did not add @PWA annotation.
Answer from Vaadin Team: There is possibly sw.js registered by a previous app you have used on the same computer. So probably unregistering service workers from browser settings will help, Browser registers service workers against the URL, so if you try out different apps locally, the registrations collide with localhost.
Solution: After adding the annotation, the exception disappeared.
Thank you, very much, Mr.Tatu for your help.
QUESTION
First I'm a newbie in GPS system. I have GPS coordinates in WGS-84 receive from a basic GPS in USB. I want to calculate the distance beetween this two point. But I want the plane distances. So I have first to convert this coordinates to an other CRS example "EPSG:2154" for Lambert 93. And after calulate the distance. I try to use Geotools but the examples in the docs are not releveant for me and I d'ont understand how to do this. I thought first I have to found the matching transform like this :
...ANSWER
Answered 2021-Dec-17 at 10:38If you simply want the distance between two GPS points then you can use the GeodeticCalculator to calculate this in metres (and the Units library to convert it to any distance unit you like:
QUESTION
I am trying to use GeoTools to transform between two coordinate systems, one in meter and the other in degree, but no matter what i try the converted values are not correct. I have tried to follow other examples using the same code, but for some reason it fails to convert between these two coordinate systems: [EPSG:3044] -> [EPSG:4326] (WGS 84)
I am parsing the WKT for both CRS and then transform it using GeoTools - below is my current code, together with my results:
EDIT The source code has been updated to reflect the output of using WKT and the internal CRS decoder.
...ANSWER
Answered 2021-Dec-04 at 14:25So the correct transformed coordinate would be: (56.4336819°, 4.1353377°)
Maybe your source coordinate is inaccurate because it is not in the area where the coordinate system is used.
From epsg.io:
Area of use: Europe between 6°E and 12°E: Austria; Belgium; Denmark - onshore and offshore; Germany - onshore and offshore; Norway including - onshore and offshore; Spain - offshore
Your coordinate is east of Africa, in the Indian Ocean.
If I'm using for example coordinates from Austria, I get the following output (in Java):

CQL and ECQL CQL (Common Query Language) is a query language created by the OGC for the Catalogue Web Services specification.
...ANSWER
Answered 2021-Nov-23 at 14:14GeoTools can convert most (many?) filter objects to SQL before sending them to a JDBCDatastore but it usually depends on which database you are targetting. See, for example, org.geotools.data.postgis.PostgisFilterToSQL - you could do something like:
QUESTION
I am trying to use V-Leaflet-Editable in a Vaadin Flow 14 app.
I have added the below in the pom.xml
...ANSWER
Answered 2021-Oct-25 at 05:56The add-on version that you are trying to use if for Vaadin 8.x versions. Add-on architecture is totally different in Vaadin 14 that you are using, so it is not compatible, unless you wrap that component using Vaadin Multiplatform Runtime.
If you only need to draw circles using the API, you can use a newer Leaflet integration. If you need to allow your end users to draw the circles on a map, then a similar Leaflet.Editable add-on for Vaadin 14 would be needed. I (the author of v-leaflet-editable add-on) don't have active plans to work on such, until I start a migration of my large hobby app to a newer Vaadin version, but if you master front-end technology, it should be rather easy to implement it by yourself or purchase one.
QUESTION
In our application (Java, Geotools 25, PostGIS) we have forms where the user can input some data which will be used to create a new features. In the database (PostGIS) there are more columns than there are fields so some columns will be empty. For some of these 'empty' columns there are default values defined in the database. Geotools however seems to always insert null for these columns.
In code I have a SimpleFeatureStore and I create a SimpleFeature based on the user input. When I'm inserting new Features (store.addFeatures()) the final SQL that is created by Geotools is an INSERT INTO statement which contains null values for all the columns which are not 'in the form', but again some of these have default values in the DB. Since Geotools explicitly sets the value to null the default value is never used.
Is there a fix or workaround I can try to resolve this issue so I can just let the DB insert default values when no value is supplied?
...ANSWER
Answered 2021-Oct-08 at 13:13The DataUtilities class provides a defaultValues(SimpleFeatureType ) method that you can call to get the value defined in the PropertyDescriptor (though by default this is null). You can define the default value for any or all of your attributes in your SimpleFeatureType.
I would use some code like:

Install geotools
You can use geotools like any standard Java library. Please include the the jar files in your classpath. You can also use any IDE and you can run and debug the geotools component as you would do with any other Java program. Best practice is to use a build tool that supports dependency management such as Maven or Gradle. For Maven installation, please refer maven.apache.org. For Gradle installation, please refer gradle.org .
