ArcGIS Pro vs ArcMap: A Comprehensive Guide for Water Resources Engineers

Water resources engineering is a field that relies heavily on accurate and efficient geospatial analysis. ArcGIS Pro and ArcMap are both powerful tools in the ArcGIS suite, each with its own set of features and advantages. In this article, we will explore the differences between these two applications and discuss which one might be better suited for water resources engineers. We will also examine the evolving landscape of GIS software and provide recommendations based on the latest developments.

Introduction to ArcGIS Pro and ArcMap

ArcGIS Pro is Esri's flagship GIS (Geographic Information System) application, designed for advanced spatial analysis and desktop mapping. It was introduced as a complete re-imagining of the traditional ArcMap interface, incorporating modern user interface elements and leveraging cloud capabilities.

ArcMap, on the other hand, has been a long-standing and widely-used GIS application. It has been the go-to tool for geospatial analysis for many years, with a robust set of features and a strong user base.

Differences Between ArcGIS Pro and ArcMap

Modern User Interface

ArcGIS Pro uses the Windows Ribbon framework, which provides a more modern and intuitive interface compared to the traditional ArcMap interface. This modern design enhances usability and navigation, making it easier for water resources engineers to work with complex datasets.

64-bit Capabilities

ArcGIS Pro is a native 64-bit application, which means it can handle much larger datasets and more complex operations without running out of memory or crashing. This is particularly important for water resources engineers who often work with large hydrological datasets, such as millions of database records.

2D and 3D Visualization

ArcGIS Pro supports advanced simultaneous visualization in 2D and 3D, taking full advantage of multicore and GPU hardware. This capability is crucial for detailed spatial analysis and visualization, which are essential in water resources engineering.

Cloud Integration

ArcGIS Pro is designed with cloud integration in mind, allowing seamless sharing and publishing of geospatial data across ArcGIS Online and ArcGIS Enterprise. This is particularly beneficial for water resources engineers who need to collaborate with colleagues and share data across different projects and organizations.

Hydrology Tools

In terms of hydrology tools, ArcGIS Pro has all the tools available in ArcMap, and it features a new type of network data structure for streams, which provides a more flexible and efficient way to model and analyze stream networks. Additionally, ArcGIS Pro introduces new capabilities in the Arc Hydro toolset, particularly those that are exclusive to Pro, making it a more powerful tool for hydrologists.

Transition from ArcMap to ArcGIS Pro

The transition from 32-bit ArcMap to 64-bit ArcGIS Pro is a significant improvement for water resources engineers. In my experience, I was unable to merge millions of database records without crashing ArcMap, but ArcGIS Pro handled the task with ease. This is a compelling reason to invest the time to learn and adapt to the new interface and tools in ArcGIS Pro.

Current Landscape and Future Trends

Esri is actively phasing out ArcMap and promoting the use of ArcGIS Pro. As a water resources engineer, it makes sense to start familiarizing yourself with ArcGIS Pro now, especially if you plan to work in this field for the long term. Learning ArcMap is still a viable option, but the future of ArcGIS appears to lie with ArcGIS Pro.

Recommendations

Based on the current landscape and future trends, here are some recommendations for water resources engineers:

Learn ArcGIS Pro now, as it offers a more modern and efficient interface and better support for large datasets and cloud integration. Stay informed about the latest updates and releases from Esri and participate in community forums and webinars to stay up-to-date with best practices and new features in ArcGIS Pro. Consider using ArcGIS Pro for your projects to take advantage of its advanced capabilities and future-proof your skillset.

As for students and new users, QGIS (Quantum GIS) is a free and open-source option that is well-suited for beginners who want to learn GIS software without the high cost of Esri licenses. While it may not offer all the specific features of ArcGIS Pro, it provides a solid foundation in GIS concepts and is a valuable tool for beginners.

In conclusion, while both ArcGIS Pro and ArcMap can be used for water resources engineering, ArcGIS Pro offers more advanced features and a better future outlook. As Esri continues to phase out ArcMap and promote ArcGIS Pro, it is advisable for water resources engineers to familiarize themselves with the new tools and capabilities of ArcGIS Pro.
