Insight for a
Changing World

The Complete Platform for Earth Observation

Organizations around the world in the public, private, and nonprofit sectors are using geographic information system (GIS) technology as a complete platform for earth observation to accelerate scientific data exploration. Interoperable and open, Esri's ArcGIS platform gives you the power to collect, manage, model, and share geospatial data.

Esri improves decision-making with software and services by combining information from many independent sources such as enterprise data warehouses, Global Earth Observation System of Systems (GEOSS), and Esri's authoritative Living Atlas of the World. Reveal deeper insights from your GIS data, remotely sensed earth observation data, big data, real-time data streams, spreadsheets, and more.

Imagery and Remote Sensing

Image collections are enabling us to map, measure, and monitor virtually everything on or near the earth’s surface. Imagery and its general raster format enable rich analysis. In turn, these analyses enable more meaningful insights about the challenges you want to address. ArcGIS is a complete imagery and remote sensing software platform, giving you the power to collect, process, analyze, manage, and share imagery.

An Open Platform for Innovation

ArcGIS is a powerful open and interoperable platform that is designed to support individual projects and scale to complete enterprise systems. Many of our core technologies are released as open specifications. We also support open standards, participate in standards development, and we integrate open data sharing. Hundreds of open-source solutions are made available on the developer collaboration platform GitHub.

Spatially Intelligent Apps

Discover how scientists are effectively communicating with policy-makers and stakeholders by transforming geospatial data into actionable information to make better and more informed decisions with powerful geo-enabled analytical apps. Apps are lightweight computer programs designed to run on the web, smartphones, tablets, and other mobile devices. Many of the powerful GIS apps below have been built to run on any device, without requiring any coding.

The Ecological Tapestry of the World

This interactive web app displays information about ecological structure based on the most detailed global ecological land units (ELUs) map in the world. The ELUs are a mosaic of almost 4,000 terrestrial ecosystems defined and modeled as unique combinations of bioclimate, landform, geology, and land cover. Use this app to understand global ecological patterns and processes for planning and use of natural resources.

Landsat Explorer

This web app allows you to navigate the world with Landsat satellite imagery. Landsat takes images of the planet to reveal its secrets, and it sees things in the electromagnetic spectrum, including what’s invisible to the human eye. Different spectral bands yield insight about our precious and continually changing Earth. With ArcGIS, explore Landsat’s massive volume of data using this simple but powerful web app.

Arctic DEM Explorer

This web app enables you to explore Arctic elevation based on the Polar Geospatial Center’s Arctic Digital Elevation Model (DEM). This app accesses server-side functions for displaying multiple elevation derivatives, analyzing changes over time, calculating profiles, generating user-defined contour intervals, and exporting source data. This app also provides access to the Arctic Landsat imagery that is updated daily.

Ecological Marine Unit Explorer

With this web app, discover Ecological Marine Units (EMU’s), which are a distinct and statistically categorized collection of 37 ecologically significant ocean water types. Commissioned by GEO, the EMU project is an innovative public-private partnership led by Esri and the USGS. Users can now gauge indicators of positive or negative trends and use data to make informed decisions that preserve marine environments.

Water Balance App

Explore changes in freshwater availability with this new Water Balance App. Interrogate and explore data from NASA’s Global Land Data Assimilation System (GLDAS). Analyze long term trends, such as how water recharge or depletion occurred, how much of the rain becomes runoff, how much evaporates, and how much infiltrates into the soil. Aggregate the time series into annual time steps to visualize seasonal variation.

Drought Tracker

This app visualizes the ever changing drought conditions in the conterminous United States, using the Drought Monitoring data. To see the drought intensity and history, select a location and explore the graphs and timeline for any week going back to 03/01/2000. This app uses data from the National Drought Mitigation Center, the US Department of Agriculture, and the National Oceanic and Atmospheric Administration.

Extreme Heat

This Story Map Journal app examines the growing public health concern of extreme heat. It contains sections users scroll through to view a combination of narrative text with interactive maps, images, and embedded content. Created by the National Oceanic and Atmospheric Administration (NOAA), this app shows how prolonged periods of unusually hot weather have real potential to be dangerous to human health and safety.

Occupations Vulnerable to Extreme Heat

This app is a Map Series story map that shows where workers in the conterminous United States are vulnerable to extreme heat. Maps in this tabbed series display county-level and tract-level data, based on the US Census Bureau's 2011-2015 American Community Survey. It focuses on workers in four occupational areas, including farming, fishing, and forestry, construction/extraction, manufacturing, and food preparation.

This web app counts the number of days in a year when conditions of temperature and humidity pose a considerable concern to human life. The map is based on the average of 20 Earth System Models developed for the Coupled Model Intercomparison Project Phase 5, under scenarios RCP26, RCP45 and RCP85. This app displays the temperature and humidity on any global location for a given year in comparison to the threshold.

Future Heat Events

This web app is a powerful tool to view how temperatures are changing, visualizing both historical data and future projections of temperature. The map can be animated to play through the years; visually depicting the total number of days with temperatures over 95° F from 1950 to 2005, with future scenarios over the period 2006-2100. When you click on a location, the temperature is graphed to show the local trend.

Heat Events and Social Vulnerability

This app combines future heat (temperatures over 95° F) and CDC’s Social Vulnerability Index 2014 to visualize the projected impact in the United States as number of heat days increases. The social vulnerability is ranked for each county on social factors and grouped into four themes including socioeconomic status, household composition and disability, minority status and language, and housing and transportation.

Global Heat Action Plans

This Cascade story map app combines narrative text with maps to show how cities around the world are including extreme heat in annual disaster response planning initiatives. This web mapping application is a crowdsourced repository of heat action plans and an early warning system for extreme heat. These Heat Action plans enable broad scale initiatives and interventions during life-threatening periods of heatwaves.
