In the recent Geo Data Science projects, the 3D geovisualization tool plays an important role in several application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management  In recent years, ESRI has developed I3S or indexed 3D scene layer which is the delivery format specification for scene layers. It aims to be used to represent different types of 3D data such as 3D building models, integrated mesh, point clouds, and much more. The advantage of I3S is its ability to stream large 3D datasets through the web with high performance and scalability. …
Most websites on the internet are built using WordPress. It is one of the best CMS. As a beginner, you may try learning with Wordpress.com to create a website and host with WordPress. However, the free site from Wordpress.com always comes with annoying advertisements somewhere on your web. Of course, you won’t earn money from that.

Nowadays, the 3D texture building model plays a big role in a variety of application domains such as game development, urban planning, Smart Cities, indoor/outdoor pedestrian navigation, environmental simulations, real estate, cultural heritage, facility management, and much more. One of the main advantages of 3D models over 2D is that it gives a better impression and understanding of the area to the users, especially when the model comes with textures.
However, generate building models with textures is always pricey. You need to get high-resolution images from drones/UAV/Satellites and do long post-processing. …
This article is a very short tutorial for installing PostgreSQL 12/ PostGIS on the Ubuntu system. It is a production note which I initially wrote for myself to install PostgreSQL on several machines. The explanation is kept very short and straight to the result.
$ sudo apt update
$ sudo apt install postgresql-12 postgresql-client-12
$ systemctl status postgresql.service

In data science projects, you may have a data table that contains country data like country name, country code, etc. But, different data sets usually provide data in different country data formats or attributes; for example, “Germany” can be recorded as “GER”, “Germany”, “DE”, “Federal Republic of Germany”, country code — 276, etc.). This would cause you some difficulties to join tables, data aggregation, data analysis, or data visualization.
This article introduces PyCountry, a Python library for completing the country data from the country database to ready your dataset to be matched or aggregated to others.
Let’s get started~

You can easily take a quick note, short report, tutorial document, etc. with the Microsoft Word. And, you might want to share the document content with some of your friends, colleagues, clients as a web document (.html)) or Markdown document (.md). In the…
The recent technology of virtual globe-based 3D visualization is a unique opportunity to facilitate advanced analysis and visualization tasks in a variety of application domains such as urban planning, indoor/outdoor pedestrian navigation, environmental simulations, cultural heritage, or facility management. One core data which make this concept come true is the development of the CityGML models by Open Geospatial Consortium (OGC — https://www.ogc.org/). CityGML is the global data model schema for describing 3D geo-spatially-enabled urban models. There are more and more cities that provide open-source CityGML models publicly.
