3、 is ArcGIS Explorer?1.1 What is GIS?ArcGIS Explorer is GIS (geographic information system) software. GIS can be used to store geographic data, draw digital maps and analyse the content of the maps based on attribution data associated with the objects which make up the map. Map data is organised into

4、 layers, so that the user can choose which layers they want to view or query. For more information on GIS see the references in section 5.3.1.2 ArcGIS softwareThis guide is an introduction to ArcGIS Explorer Desktop, which is one of a number of GIS products produced by Esri, some of which have confu

It is expensive to buy and only available for the Windows oper

10、 Old Bodleian· The Radcliffe Science Library Training RoomArcGIS Explorer is free to download onto your own machine. Instructions of how to download ArcGIS Explorer can be found in section 4 of the course book for ArcGIS Explorer: An Introduction (see section 5.2).2.2 Open ArcGIS ExplorerThis i

11、s the ArcGIS Explorer icon.When you open ArcGIS Explorer you should see something like this:RibbonContents windowMap windowThe Explorer window consists of three panels: the ribbon, the contents window and the map window. The RibbonThe ribbon is where you will find most of the controls in Explorer. T

12、he ribbon has different tabs (here Home and Display) with the controls on each tab organised into groups. The ribbon has different tabs (here Home and Display) depending on the type of content highlighted in the content window. The Contents WindowThe contents window will lists the files open in the

13、map. An icon next the name of the what the is and a check box tells you whether the layer is visible. Clicking on the cross next to the show you the symbol used on the map for that file. You can hide the contents window so that the map can fill the entire width of the Explorer window and the content

14、s it is just a tab on the left hand side of the map window by clicking on the push pin in the top right corner of the contents window. The Explorer ButtonYou will also find some controls under the Explorer Button in the top left of the screen (see screenshot below).2.3 Moving around the map You can

19、 a map3.1 Types of dataData stored and displayed in a GIS can be vector data, raster data or gridded data. Explorer does not deal with gridded data, so only vector and raster data are discussed here. See section 2.2 of the Course Book ArcGIS: An Introduction or one of the many textbooks on GIS for a

20、n explanation of gridded data.Raster data is an image composed of a grid of coloured pixels, such as an aerial photograph or scanned paper map. To visualise this data in GIS it must have spatial data associated with at least 3 points on the image. In ArcGIS this is called georeferencing and in ArcGI

21、S Explorer Desktop a georeferencing add-in is required (see section 4.1). Raster data has an optimal scale to be viewed at. Zoom in too much and the image becomes pixellated.Vector data can be points, lines or polygons. Each object spatial data and attribute data associated with it. The spatial data

22、 describes the location of the object while attribute data gives more information, such as type of feature, name and numerical data. Vector data is redrawn at different scales and the symbol used to represent the data can be changed. To add data to a map in ArcGIS Explorer go to Add Content in the M

23、ap group on the Home tab.ArcGIS Online find content available from (vector or raster data)ArcGIS Layers (.lpk, .lyr or .pkinfo) layers created in ArcGIS Desktop. Symbology is retained.

When this type of data is added to an

28、g, presentations, etc, such as a logo. 3.2 Sources of data· Base maps provided with ArcGIS Explorer· Public domain or licensed maps· Scanned and georeferenced printed maps and · Database/spreadsheet with spatial referencing. In ArcGIS Explorer this data must be points, not lines

29、or polygons. · Draw your own data3.3 BasemapsA number of basemaps are available in ArcGIS Explorer Desktop. They are streamed off the internet, so will only be available when you have an internet connection. It is not possible to modify a basemap and the basemap must be the lowest layer (i.e. a

30、ll other content is drawn on top of the basemap). If you do not want to use a basemap select the Clear basemap option under the Basemap menu (see below).3.4 Drawing ObjectsUser-drawn objects drawn in ArcGIS are called notes. Go to the Create group on the Home tab and select the type of object you wo

31、uld like to create. When drawing lines or polygons you can remove the previous vertex you added by right clicking, but once the object is complete you cannot edit the vertices.Notes have a title and note content which can include text, links and html.How an object is represented graphically in ArcGI

32、S, for example the note above is depicted as a red push pin, is called its symbology. You can change the symbology of a note in the Appearance tab. The screenshot below shows some of the options available for a polygon.3.5 SavingThere are a few different things you can save in ArcGIS Explorer.To sav

33、e a view got to View in the Create group on the Home tab. This saves this horizontal position and zoom level within the map you are viewing.To save a whole map go the Explorer button in the top left. You will have the choice under Save as to save your map as an ArcGIS Explorer map or as a new basema

34、p. In both cases you are saving a *.nmf file. The difference is that if you save it as a basemap it will be a static map, i.e. it will not be editable. When you save your map you are not saving the data that you see on the map, but a list of which files contain the data and information about how you

35、 want to view the data. That is except for note data which is saved as part of the map. Therefore it is important not to move or rename the files that contain the data used in your map.4 Further features of ArcGIS Explorer4.1 QueriesIn ArcGIS Explorer you can run queries on vector data. You can quer

36、y the attribute data or spatial data. For example, an attribute based query would be “Which cities have a population of more than 1 million?”. Spatial queries question the spatial relationship between features. For example, “Which roads cross the River Thames?”. For more information on queries see s

37、ection 3 of the course handbook for ArcGIS Explorer: Intermediate (see section 5.2).4.2 Add-InsYou can extend the functionality of ArcGIS Explorer Desktop with Add-Ins downloadable from . Add-Ins include:· Georeferencing create spatial data for your raster image so it can be shown on your map&#

39、 Zoom to map scale zoom to a map scale chosen from a user-defined list of scales4.3 PresentationsArcGIS Explorer can also be used to create presentations where each slide is a map view. When the presentation is run ArcGIS will transition smoothly from each map view to the next. It is possible to add

40、 image overlays and text to the slides. For more information see the Creating a presentation section of ArcGIS Explorer online help (gisexplorer/1700/en/). An add-in is available to convert the presentation into PowerPoint format.5 Sources of help5.1 Online helpArcGIS Explorer HelpOnline help pages for ArcGIS ExplorerPress F1 while ArcGIS Explorer is open or go to ArcGIS Explorer Desktop Product WebpagesWith general information and links to forums, videos, help etc5.2 CoursesArcGIS Explo
