QUESTION
I am working with a large amount of CityGML 3d building data (LoD2) and imported the data using the 3D City Database (and its Importer/Exporter tool) (see https://www.3dcitydb.org/3dcitydb/) which creates a new schema in the database and uses java routines to translate the XML-style geodata to PostGIS compatible database input.
The information (spatial and non spatial) for each building is then written to different tables, where "building" table holds building meta data such as building function or street name and "surface_geometry" table holds solid and 3d surface geometries of all buildings. With columns "id", "parent_id" and "root_id" used as PKs and FKs to ensure the elements of one table can be matched to one or more elements of the other table.
Since I need 2d building footprints (or bird view polygones) for most of my analyses, I created queries to make surfaces 2d with st_force2d() before st_union()ing all 2d surface of the same building with group by on the available FK.
Are there any ideas how to improve the following code to effiecntly process a huge dataset?
The queries are

QUESTION
For a project I wanted to extend Elasticsearch and therefore need to use the package Symja. In the Github for Symja, there is a manual for the usage with Maven provided.
Since the Elasticsearch repository is build with Gradle, I also need to use Gradle instead of Maven. Testing the suggested example Symja project, the following build.gradle (which I basically generated by using gradle init and adjusted a little) imports the library flawlessly:

First of all, it seemed to be necessary to manually add all implicit dependencies plus the repositories they originate from to server's build.gradle, corresponding to the pom.xml files of matheclipse-core and of matheclipse-external:

I am getting a huge list of error when I try to run the following code with google_maps_place_picker package in flutter.
ANSWER
Answered 2021-Apr-17 at 14:08You are using import 'package:google_maps/google_maps.dart';
google_maps package only supports web. For mobile support should try out flutter_google_places, google_maps_flutter or any other package.

QUESTION
I am trying to create a program in Python that will let me check the Geodetic Transformations that the geodesy app in my survey software spits out. I have a test point and know that my program currently returns total rubbish.
The formula that I am using is the 7 Parameter Halmert Transformation:
Vb = T + (1 + s * 10^−6)•R•Va
My code is:
...ANSWER
Answered 2020-Jul-07 at 07:26The Helmert transformation is for mapping a point in cartesian (ECEF, aka earth centred earth fixed) coordinates relative to one coordinate system, to the cartesian coordinates relative to another coordinate system.
If you want to transform lat,long,height coordinates relative to the first coordinate system to lat,long,height coordinates relative to a second, the drill is:
QUESTION
Disclaimer: I have only started using sf so I might be (hopefully!) missing something obvious here.
I have the AusGeoid2020 data which consists of 15,454,800 points and some attributes to convert between ellipsoidal heights (i.e. GPS height) and the AHD.
Although the file is large (914Mb) it's easy enough to read in:
...ANSWER
Answered 2020-Jun-05 at 05:28We can use st_as_sf as follows. The default setting would remove the columns with coordinate information (in this case, Longitude and Latitude). If you want to keep those columns, set remove = FALSE.

I've inherited a legacy Java app require JDK 7.
The app will compile, but I'm getting runtime errors which look like Hibernate entityManagerFactory issues.
The strange part is this app works on another developers machine. He even sent me his Tomcat directory, I have tried it on a Mac and on an Ubuntu machine. No matter where I run it, the runtime errors persist.
I think the problems is an init method in entityManagerFactory class,

Install geodesy
You can use geodesy 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 geodesy 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 .
