In the field of Geographic Information Systems (GIS), software selection is crucial for professionals and enthusiasts alike. Different GIS software comes with unique features and advantages, catering to various scenarios and requirements. Here, I recommend five excellent GIS software options, including free domestic software and popular foreign software.
1.GISBox
GISBox is a comprehensive and practical free platform for editing, converting, and publishing tilted photography OSGB/3Dtiles, providing one-stop 3D GIS processing services with unique advantages in several areas.
1)Convenient Scene Editing:
Supports the import of multiple file formats such as GLTF, FBX, OBJ, SHP, GEOJSON, OSGB, with real-time preview upon import. For tilted photography OSGB models, it allows for online editing operations such as broken surface repair and terrain alignment. It also allows for the import of SHP data by selecting an area on the map and can generate urban building models with one-click elevation, simplifying the model creation process.
2)Conversion of Various Formats:
Covering multiple types of slicing, including tilted photography slicing, general model slicing, terrain slicing, image slicing, point cloud slicing, and reversed slicing of tilted photography, to meet different data processing needs.
3)Multi-protocol Service Publishing:
Supports the publishing of protocols such as 3DTiles, Terrain, and Wmts, as well as the publishing of aggregated services. After slicing, different formats of models and data files can be automatically published. After publishing, users can quickly preview the sliced content and view the publishing path with one click.
This tool handles everything from scene editing, slicing conversion, to distribution services in one streamlined process, eliminating the need to switch between multiple software, significantly improving work efficiency. It also has wide compatibility, supporting multiple operating systems such as Windows, Mac, and Linux (deb, rpm). However, due to its relatively lower popularity compared to other software, the scale of related technical documentation and user communities still needs further development.
2.ArcGIS
ArcGIS is a professional GIS desktop application developed by Esri, offering advanced map creation, spatial data analysis, and 3D visualization capabilities. It supports multi-layer editing, real-time collaboration, big data processing, and deep learning integration.
In terms of data processing, ArcGIS supports multiple data formats and can efficiently import, edit, and manage data. Its mapping function is top-notch, allowing users to easily create professional-level maps, with impeccable color matching and annotation details.
ArcGIS boasts a vast user community, meaning users can easily access a plethora of tutorials, cases, and technical support when encountering problems. However, its high learning curve and relatively expensive price are not very friendly to smaller teams or individual developers.
3.QGIS
QGIS is an open-source GIS software, which gives it a significant cost advantage, especially suitable for users with limited budgets. It provides basic map browsing, data editing, and analysis functions, meeting most common GIS needs.
QGIS features a simple and intuitive interface that is easy to get started with, particularly friendly for beginners. Additionally, it has a rich plugin library. By installing plugins, users can expand its functionality to perform operations such as advanced spatial analysis and data visualization. Furthermore, QGIS's cross-platform capability allows users to work on Windows, Mac, Linux, and other operating systems. However, compared to some commercial software, its performance in processing large-scale data may be slightly inferior.
4.MapInfo
MapInfo occupies a niche in the GIS market with its ease of use. It focuses on map visualization and basic spatial analysis, making it a good choice for users who do not need complex functions but only require simple map creation and data analysis.
The software's operating interface is simple and clear, allowing users to quickly get started. It supports the import of multiple data formats and can conveniently create and edit map layers. In the commercial sector, such as marketing and logistics distribution, MapInfo is often used for the analysis and display of geographical data, helping businesses make more reasonable decisions. However, its functionality is relatively limited and may not be suitable for in-depth scientific research analysis or complex engineering projects.
5.Google Earth Engine
As a cloud-based GIS platform, Google Earth Engine's biggest highlight is its powerful data analysis capabilities and vast data resources. It integrates a large number of satellite imagery and geographical datasets. Users can directly analyze and process data on the platform without spending a lot of time downloading and storing data.
With Google's powerful computing capabilities, it can quickly process large-scale data for complex analyses such as land cover change monitoring and forest resource assessments. Moreover, it provides simple JavaScript and Python APIs for developers to customize developments. However, it has higher requirements for network connectivity, and the user experience may be greatly reduced in cases of unstable networks.
Conclusion
These five GIS software options each have their strengths. Whether you are a professional seeking comprehensive functionality or a beginner prioritizing cost and ease of use, you can find a suitable software among them. When choosing GIS software, we should comprehensively consider factors such as personal needs, budget, and technical proficiency to select the GIS tool that best meets our requirements.
