2 Analysis Understand Places Determine relationships Find locations Detect patterns Observe change Make predictions analysis noun 1 a detailed examination of the structure and content of something. 2 a statement of the results of such an examination. insight noun 1 the ability to gain a relatively rapid, clear and deep understanding of the real, often hidden and usually complex nature of a situation, problem, etc.

7 Visualization Display defined by author and service GraphicsOverlay, CsvLayer FeatureLayer ServiceLayer KmlLayer Display defined by your app code

8 Visualization Renderers: Unique Value, Class Breaks, Temporal Symbols: Marker, Text, Line, Fill Generate Renderer operation - Returns a renderer object for the input classification method and color ramp Use for UniqueValues or ClassBreaks Samples the data within the service to determine correct breaks Exposed as GenerateRendererTask new GenerateRendererTask( ) Can use the MapService to generate a renderer for - FeatureLayer if using feature service associated with map service - GraphicsOverlay containing the results of a query against map / feature service

11 Geometric Operations Geometric calculations - Determine spatial relationships - Determine distances between geometries - Derive new geometries as the Union, Intersection, Difference GeometryEngine Operates on arrays of individual geometries Not bound to data or services Performs a stateless computation Very efficient synchronous operations Executes within your app process The foundation for many workflows - e.g. click > buffer > query > project > display

14 Query Data Subset data by any combination of criteria - Attribute where clause e.g. POP >= Query geometry - Time extent Primary table and related tables

15 Query Data QueryTask.ExecuteAsync - Execution of query on server - Organize results using GroupBy, OrderBy - Obtains statistics for data: Sum, Min, Max, Avg, Count, StandardDeviation, Variance FeatureTable.QueryAsync - Service-FeatureTable QueryAsync executes on server - Can force local query against cached data - Geodatabase-FeatureTable QueryAsync executes locally

18 Geoprocessing A framework and tools for powerful GIS analysis Tools can be chained together to model entire workflows then automated Executes: - On device using LocalServer:- only Java,.NET, and Qt SDKs - ArcGIS Server:- publish your own services - ArcGIS Online:- services hosted by esri

19 Geoprocessing Framework supports two modes: - Sync lighter weight service type for fast operations which returns results directly - Async longer running jobs with ability monitor progress then fetch results Published from results/packages which validate the inputs, processing and outputs Access from the API via the Geoprocessor task When using LocalServer use the API to administer LocalGeoprocesingServices

20 Geoprocessing Important considerations for building geoprocessing models to run as a service Use layers for project data Use local data to ArcGIS Server / LocalServer Write intermediate data to memory Preprocess data used by your tasks Add attribute and spatial indexes Use synchronous rather than asynchronous where possible Avoid unneeded coordinate transformations Reduce data size

23 Network Analysis Network-based spatial analysis Configurable transportation network data model Fine grained control over the calculations performed including: - Network costs e.g. time, distance, slope, traffic - Barriers (point, line, polygons) - Time windows - Vehicle capacities / capabilities Different implementation patterns depending on the type of analysis
