تحميل كتاب تدريبات GIS باستخدام برنامج ارك GIS Tutorial for ArcGIS Pro

استكمالا لسلسلة تعلم نظم المعلومات الجغرافية GIS باستخدام برنامج ArcGIS Pro نقدم لكم في هذه المقالة كتاب تدريبات GIS باستخدام برنامج ارك مجاناً GIS Tutorial for ArcGIS Pro for free ، من تأليف Wilpen L.Gorr ، Kristen S.Kurland . 

The ArcGIS platform is an integrated collection of GIS software packages and apps developed by Esri that work seamlessly across desktop computers, the Internet, and mobile devices. The tutorials in this first chapter will familiarize you with some major components of this platform: ArcGIS Pro, ArcGIS Online, and Explorer for ArcGIS. You’ll use additional ArcGIS apps and packages in other chapters. 

ArcGIS Pro, the major package taught in this book, is a 64-bit desktop GIS application that uses the Microsoft ribbon interface for 2D and 3D map authoring, analysis, and web publishing. The interface makes relevant tools visible and available for whatever work you’re doing in GIS. ArcGIS Online is Esri’s cloud solution for interactive web mapping and spatial data sharing. Maps that you create in ArcGIS Pro can be published to ArcGIS Online. Then, once in ArcGIS Online, maps can be accessed in web browsers and in mobile-device apps. Explorer for ArcGIS is a simple interactive viewer for your online maps. 

In this chapter, you will work with a finished map that has the locations of urgent health care clinics in Allegheny County, Pennsylvania. These clinics are federally qualified health centers (FQHCs) that provide subsidized health care for underserved populations and MedExpress clinics that provide private health care. In part, both FQHCs and MedExpress centers are low-cost alternatives to hospital emergency rooms. You will examine the finished map’s components while navigating through user interfaces and around mapped features. 

In the process, you’ll learn that both the publicly funded and private-sector urgent health care clinics are well ocated in interesting spatial patterns. 

You must have ArcGIS Pro and the data for this book installed on your computer for this tutorial and the rest of the book. If you are taking a GIS class in a college or university, your instructor will provide access to ArcGIS Pro on computer lab computers or your own computer. If you are not in a class or organization that licenses ArcGIS, you can sign up for a free trial at Website http:pro.arcgis.com. The first time you start ArcGIS Pro, you will be prompted to license the software. To license the software, you must have an ArcGIS Online or Portal for ArcGIS Account. 

Before starting work on your computer, take time to review some key terminology for ArcGIS Pro projects and spatial data. 

• A project is a file, with the extension .aprx, that contains one or more maps and related items. For example, you’ll open project Tutorial1-1.aprx in ArcGIS Pro after this introduction. The project has two maps, Health Care Clinics and Health Care Clinics_3D, plus other project items. 

• A project has a home folder of your choice. The home folder of Tutorial1-1.aprx is Chapter1\Tutorials. If you installed this book’s data on the C drive of your computer, the location of the Tutorial1-1.aprx project is C:\EsriPress\GIST1Pro\Chapter1\Tutorials\Tutorial1-1.aprx. 

• A file geodatabase is a folder, with the extension .gdb, that stores one or more feature classes, Rasters, and other related files. Although there are many other file formats for storing spatial data, the file geodatabase is a preferred ESRI format. The data used in Tutorial1-1.aprx is in the file geodatabase Chapter1.gdb, stored in the Chapter1\Tutorials folder on your computer. A project does not store spatial data used to make maps but instead stores connections to spatial data, such as a file geodatabase, that is stored elsewhere on your computer, ArcGIS Online, or other locations. 

• A feature class is composed of spatial data and is the basic building block of GIS for storing features that can be graphically displayed on a map. Feature classes have corresponding attribute data for each feature. For example, Chapter1.gdb has a feature class named FQHC that has point locations for all FQHCs in Allegheny County, along with attribute data including the FQHC name and address. Chapter1.gdb has many more feature classes, one of which is Municipality, which has boundaries for all municipalities in the county (including the City of Pittsburgh). Yet another feature class is Streets, which has center lines for all streets in the county. 

• A raster dataset (or raster) is the other major type of spatial data for mapping. Quite often, a raster is a stored image made up of pixels—square areas with assigned colors so small that you can’t see them individually until you zoom close in. In general terms, a raster is a rectangular table with numbers in cells (the pixels), with cells referenced to geographic coordinates. For images, the stored numbers correspond to assigned colors. 

• A map layer is a feature class or raster as visualized in a map, and a map is a composition of map layers overlaying each other. The layers are chosen and symbolized by you to serve a given purpose. It’s important to understand that an ArcGIS Pro project is a file that stores your maps, but the spatial data (feature classes and rasters) that comprises maps is stored elsewhere on your computer, a local area network, or in the cloud on the Internet.
