NCEP Climate Forecast System Reanalysis (CFSR) Monthly Products, January 1979 to December 2010. The data used in this tutorial is from the NCAR Research Data Archive: An overview of the Multidimensional Analysis toolset.Working with a multidimensional raster layer.An overview of multidimensional raster data.For more information on these topics, see the following: You then explored your data using temporal profileĬharts. To aggregate the data into yearly maximum temperature and calculateĪnomalies. Surface temperature data to your map and used geoprocessing tools Use the anomaly CRF dataset to find other interesting areas. Here, you can see a distinct, steady increase in temperature over time-one of the many impacts of global climate change. The temporal profile for this part of the world is different from the east-central Pacific. Next, you will use geoprocessing tools andĬharting to explore sea surface temperature change over time and Layer to ArcGIS Pro, depicting sea surface temperature from the National Centerįor Atmospheric Research (NCAR) Research Data Archive. In this tutorial, you willĮxplore some of the ways you can process and display scientificĭata using multidimensional raster datasets.įirst, you will add a multidimensional raster Layers, mosaic datasets, and multidimensional raster datasets

You can work with scientific data in ArcGIS Pro using multiple formats: space-time cubes, multidimensional Scientific data and to incorporate the data into GIS World, it is important to work with and understand Scientific data for temporal and spatial analysis. In ArcGIS Pro, you can visualize and process

Instead, it has a rich library of functions that make it easy to author complex calculations.Īrcade is used throughout the ArcGIS Platform to provide a portable mechanism for defining and sharing expressions. implicit return var myArray = Īrcade is simple and does not have many of the programming constructs that exist in other programming languages. ( $feature.POP_2010 / $feature.POP_2000) * 100 // explicit return var myArray = explicit return return ( $feature.POP_2010 / $feature.POP_2000) * 100 // implicit return This is referred to as an implicit return. In multi-line expressions, Arcade will return the last statement even if the keyword return is not used.

Implicit returns allow Arcade to be used for simple, single-line expressions and also for full multi-statement scripts. $feature.landValue * 100 Returning values from your script The expression below accesses a field named landValue and multiplies it by 100. This represents a feature from a service or a layer, and contains a geometry and set of attributes. In the snippet below the expression references the $feature global variable. 'Hello World'Ī more common use of Arcade is for performing a calculation with layer fields and using them for label expressions or data-driven visualizations. The following example contains a single statement that evaluates to a string. This includes apps developed with the ArcGIS Pro and Runtime SDKs, and the ArcGIS API for Javascript. It is intended solely for evaluating embedded expressions such as those used in the visualization, labeling, popup, and alias contexts of applications built with the ArcGIS platform. While the syntax contains similarities to other scripting languages, Arcade is not designed for writing standalone apps. In future releases, other geometry functions may be added allowing you to calculate areas and lengths, and perform simple overlay operations in more complex expressions. In the initial release of Arcade, geometries can be created and referenced. What makes Arcade particularly unique to other expression and scripting languages is its inclusion of feature and geometry data types. It allows users to write, share, and execute custom expressions in ArcGIS Pro, ArcGIS Runtime, ArcGIS Online, and the ArcGIS API for JavaScript. Arcade was designed specifically for creating custom visualizations and labeling expressions in the ArcGIS Platform. It also supports multi-statement expressions, variables, and flow control statements. Like other expression languages, it can perform mathematical calculations, manipulate text, and evaluate logical statements. Arcade is a portable, lightweight, and secure expression language written for use in the ArcGIS platform.
