kandi X-RAY | geopackage Summary

geopackage is a CSS library. geopackage has no bugs, it has no vulnerabilities and it has low support. However geopackage has a Non-SPDX License. You can download it from GitHub.

This GitHub repository was originally extracted from the Microsoft Word version of the Candidate GeoPackage Standard [version 0.8] released for [public comment] on August 6, 2013. With this repository the OGC invites collaboration and comments directed at the development and enhancement of this candidate standard. The repo tracks the latest version of the standard as it evolves. Pull requests for fixes are appreciated, and new functionality will still be considered even though version 1.0 has been adopted. The spec is done in [asciidoc] a format supported by GitHub, similar to markdown but with some features that make it better for specifications, like automatic section numbering.

Given what you describe, this warning is fully expected. If you have modified the geometry of the nodes and have not made x and y attributes consistent. Best illustrated by sample code below.

first conversion back to a graph generates a warning
second conversion after ensuring denormalised columns are consistent with geometry does not generate a warning

QUESTION

Update variable created by eventReactive in another observeEvent

Asked 2022-Feb-18 at 17:57

I'm struggling to update a reactive variable, that is created with eventReactive(), in an observeEvent() with new data.

The background is following: I have a data.frame df with some variables (x and y) and number of observations depending on the selected city (created randomly for this example). x and y are initialized with zeros. Because I need to further process df, I pass df to city_df in an eventReactive().

So far, so good. Next, I want to add new data to city_df. The computation of this new data is dependent on the "compute" actionButton (input$compute), wherefore I update city_df in an observeEvent(). I manage to read the data stored in city_df, but I am struggling to overwrite its content. Actually, I am a bit unsure if this is possible at all, but I hope that some of you could give me a hint on how to update the reactive variable city_df with the new data in this observeEvent() and have its output evaluated in the app(?).

Rather than using an eventReactive, if you use a proper reactiveVal, then you can change the value whenever you like. Here's what that would look like

Can I save a GeoDataFrame that contains an array to a GeoPackage file?

I have a geopandas GeoDataFrame with some attribute columns and a geometry column (just a regular GDF). Usually I save GDF's as GeoPackage giles (.gpkg) using:

ANSWER

Answered 2022-Feb-01 at 19:46

I believe this is just a limitation of the .gpkg format. However, I think the best workaround approach is to store the arrays as strings, like you suggested. You can easily convert them back into arrays in news gdf if you need to with ast literal_eval().

ST_Within does not return true

EPSG:2193 has coordinates in metres so it is unlikely that your values (174.82726, -41.16671) are in that projection, it is much more likely that they are in degrees (WGS84, EPGS:4326). So you need to transform your point to compare them to polygons in EPSG:2193, thus your SQL should be something like:

Slicing a large file, removing duplicates and merging into output using Pandas

Asked 2021-Feb-06 at 09:23

So, I have a geopackage with 1.25 billion features. The file doesn't actually contain geometry and only has one attribute 'id' which is a unique id. There are a lot of duplicates and I want to remove duplicated 'id' and keep only unique values. Due to the sheer amount of data present (the geopackage contains 19 GB), I went with slicing. I tried multiprocessing but that didn't work and it would have problems since I have to keep track of the unique 'id' and multiprocessing would not allow this (to my knowledge at least).

What I have:

So, here is the final script. The issue that I was having is that when you slice a geopackage file using geopandas, when you get to the end, it starts from start and doesn't stop. So I added the if statement at the end of the code to cover that.
