Quick Overview of the ArcGIS API for Python

A Pythonic GIS API
- Corresponds to best practices
- Uses standard Python constructs
- Data structures with clean, readable idioms
Easy for a Python programmer to use ArcGIS
Easy for an ArcGIS user to script and automate their GIS

Why Python?

Popularity
Productivity
Interoperability
Solves the “two-language” problem
Scientific Python ecosystem
Community

ArcGIS Runtime Overview

Architecture

ArcGIS Runtime APIs – public APIs for multiple platforms
- Same capabilities across all APIs
- API surface is tailored to the relevant dev stack

ArcGIS Runtime Overview

Esri’s developer product for native app development
- Incorporate ArcGIS functionality into mobile and desktop applications
- Web service client and local (offline) capabilities
- SDKs for .NET (including Xamarin), Android, iOS, Java, Qt, and macOS

ArcGIS Runtime Overview

High-performance 2D and 3D mapping
Integration with Portal, ArcGIS Online, and ArcGIS Server
- Load, edit, and save web maps
- Use map, image, and feature services
- Geoprocessing for complex custom analyses
Work offline with local data and functionality
- Read local data (.mmpk, .tpk, etc)
- Geocode and Routing
- Geometric operations (buffer, etc)
- Take web maps offline
- Feature service editing and sync

Offline vs Online

Performance vs Availability

Offline Data and Services
- Sideload data/geocoders/network models for highly interactive performance
- No round-trip to a server
- Consider hybrid online + offline if appropriate
Consider Network Availability & Data Qualities:
- Do you need to edit? If not, perhaps side-loading is an option.
- Will many people get the same data? Maybe generate once, sideload often.
- Lots of data changing often? Try to sync when on WiFi.
- How fast is the network in the field?
- How consistent is the network in the field? Patchy?

Perfomance

Work on the device

GeometryEngine
- Manipulate geometry on the device
- Buffer, Union, Difference etc.
- Projection
Offline Data
- Data on the device for highly interactive performance
- No round-trip to a server
Graphics Overlays
- Dynamic Mode (smaller number of moving graphics – good interactive performance)
- Static Mode (large number of graphics – less interactive performance)
