ArcGIS is geospatial software to view, edit, manage and analyze geographic data. Esri develops ArcGIS for mapping on desktop, mobile, and web. Their motto is “Science of Where”. As such, the focus for ArcGIS is on location intelligence and analytics.
Who develops ArcGIS software?
Esri (Environmental Systems Research Institute) develops ArcGIS software. The company’s headquarters is in Redlands, California. In 1969, the company was first founded primarily for land use development. With over 40% of the market share, ArcGIS is the leading GIS software in the market today.
Who uses ArcGIS?
ArcGIS users are in a wide range of fields and industries. For example, government, education, and commercial industries use ArcGIS. But the largest user base is in the environment, military, and land planning. Because most colleges use ArcGIS, graduates are usually somewhat familiar with it.
What software is part of ArcGIS?
ArcGIS is a set of software consisting of:
- ArcGIS Pro
ArcMap is the centerpiece of the Esri suite of GIS software. It’s how users create maps from scratch. By analyzing data, they can find location patterns and trends in ArcMap. Finally, users edit data and can call it their own. The main format for ArcMap is an MXD (Map Exchange Document).
ArcCatalog is more like Windows Explorer that shows only geospatial data. In a way, it’s also like a library where you can organize and manage your GIS data. ArcCatalog is where you document and write metadata as well.
ArcGIS Pro will one day replace ArcGIS. It has several advantages over ArcGIS. For example, its main advantages are 64-bit processing, integrated 3D, and ribbon-based interface. Unlike ArcGIS, it stores your maps, data, and toolboxes as a project file (.APRX). Finally, ArcGIS Pro has tools and extensions that go a bit beyond ArcGIS.
Using the 3D Analyst extension, you can access ArcScene. ArcScene focuses on local areas like the size of a neighborhood. If you want to save a scene, its format is SXD.
ArcGlobe is a 3D application for larger study areas. Instead of the size of a neighborhood, it’s well-suited for global extents. If you’re going to use ArcGlobe, its file format is 3DD (ArcGlobe Document).
ArcGIS Extensions and ArcToolbox
By using ArcGIS extensions and add-ons, you can boost the capabilities of the stand-alone product. For example, there are extensions for GPS tracking, geostatistics and more. Each add-on has a toolset that you can use as part of an ArcToolbox.
How does ArcGIS Online relate to ArcGIS?
ArcGIS Online is a web and cloud-based platform for online uses. The main advantages of using ArcGIS Online are:
- It’s easy to build powerful web maps online that you can share and engage with the community.
- By using Collector and Survey123, field crews can collect information from the field.
- ArcGIS Online is a massive warehouse of GIS data including authoritative authors. In fact, it’s so good that it’s #1 on our list of free GIS data sources.

What is the history of ArcGIS?
Esri develops ArcGIS software. Their history as a company spans close to 50 years. Here is a breakdown of some of the key developments in ArcGIS.
In 1973, Esri is on the map by providing the first commercial statewide GIS for Maryland.
- PC ARC/INFO: Esri releases PC ARC/INFO for individual personal computers in 1987. All is command line based.
- ARCVIEW 1.0: In 1991, ArcView 1.0 is a fresh GIS software approach. It uses a GUI desktop environment.
- ARCVIEW 2.0: ArcView 2.0 combines object-oriented Avenue programming. This product was developed using a multi-platform environment in 1993.
- ARCVIEW 3.0: In 1995, ArcView 3.0 was the first full-featured GIS software. For example, it included a geoprocessing wizard with extensions for raster and 3D.
From here, ArcView skips some major releases jumping to ArcGIS 8.0x. So, ArcGIS 4, 5, 6, or 7 doesn’t exist.
In 1999, ArcGIS 8.0 combined ArcView and ArcInfo. One of the key changes was that it strayed away from Avenue in favor of Visual Basic for Applications (VBA). It also introduced its proprietary geodatabase for storing vector, raster, tables and relationships. Other key improvements included:
- Topology rules for improved error checking
- On-the-fly projections helped maintain the same projection on the map frame.
- Annotation creation in the data frame and map document.
In 2004, Esri released ArcGIS 9.0. The major update on this version was a switch to Python. In this release, users could access any tool through Python scripting language. Here is a list of highlights from this release:
- ModelBuilder became a means of stringing together a set of tools in a repeated way.
- Esri switches to Python scripting where users can automate workflow.
- Data driven pages for building a collection of maps as mapbooks.
In 2010, Esri released ArcGIS 10.0. Even now, this is still the current release of ArcGIS. In this release, ArcGIS continued with Python as its scripting language. But it brought other advancements such as:
- Feature templates for more intuitive editing and better snapping.
- Image Analysis Toolbar helped clip rasters, perform NDVI and image classification.
- Time series animation for temporal data
- Map packages for sharing layers in map documents.
