2/5/2024 0 Comments Grid field type arccatalog![]() ![]() If you try to work on this file in ArcGIS with it still open in excel it will not work. IMPORTANT you cannot work on the same file in two programs at once. Open “foliation-wt.csv” in a text editor and see that it is the same data with a comma: ‘,’ between each value ( Comma Separated Value).This will mean that excel will ask whether you want to save changes when you try to close the file, you can just select “Don’t Save” OR if you haven’t saved some changes you want to preserve in excel format you can do that now. Excel will keep the file open with all excel editable features intact, but will change the file name extension to. CSV is for storing data, it can’t store formulas, graphs, multiple sheets and other things like. Excel will warn you that some features will be lost.In save as type choose CSV (Comma delimited) (*.csv).In excel choose File>Save As and choose the location where the excel file “foliation-wt.xlsx” is stored.All columns with numbers in them only have numbers (they can therefore be recognised as number fields).īut this data is in excel format.It has Eastings and Northings and the Map projection is indicated (NZTM).It has a single header row with clearly marked fields.Here are some of the features that make this XY data suitable ![]() The data has been prepared so that it is ready to be added into ArcGIS.Open the data folder and open up the “foliation-wt.xlsx”.This is how I like to manage maps and data in ArcGIS. There is a map on the top level and a folder with data in it.Get the folder “Add XY data files” and extract it.csv format to shapefile or feature class (in geodatabase). My preferred technique is to convert from. It is also possible to convert directly from an excel spreadsheet, but this is unreliable. There are ways to open a spreadsheet directly in ArcGIS, but in my experience there are often problems. Httpv://youtu.be/vmEPsc8NnT0 Adding XY data to ArcGIS text instructions The video below covers most of the steps for adding XY data apart from the problem solving tips that are only covered on this page. By XY data I mean point data such as foliation that has a spatial (XY) component associated with it. Optionally, you can set a configuration keyword.This tutorial covers adding XY data to ArcGIS, so that you can view and work with the data in ArcGIS.Setting the domain for a raster catalog works the same way as it does for a feature class. If your coordinate system for the geometry column is unknown, you need to set the domain. Click the Coordinate System for Geometry Column button to set a coordinate system for the geometry column.Optionally, click the Coordinate System for Raster Column button to choose a coordinate system for the raster catalog.You can use underscores to separate letters. The raster catalog name cannot have spaces. Type a name for the new raster catalog.The new raster catalog will then have the same fields as the template raster catalog. You may want to use an existing raster catalog as a template if you have created additional fields in it that you want to have in your new raster catalog. Optionally, choose a template raster catalog on which to base your new raster catalog.Right-click a geodatabase and click New > Raster Catalog.These raster catalogs must be upgraded by clicking Register With Geodatabase on the ArcCatalog context menu. The SDERASTER command line loader loads raster catalogs with the 8.x schema. Otherwise, if neither of these is set, your datasets may not be visible in the display. If your coordinate system is unknown, you need to specify the domain for the geometry column. When creating a raster catalog, the coordinate system needs to be set for the geometry column. When you do not have your raster managed by the geodatabase, there is only a pointer connecting the raster catalog row to the file-based raster dataset. When a row is deleted from the catalog, it is deleted from the geodatabase. To have the raster catalog managed by the geodatabase means that the raster datasets are copied and stored alongside the geodatabase. Raster datasets within raster catalogs can be managed in two ways by the file and personal geodatabases: either managed by the geodatabase or not. You can create a raster catalog using the context menu in ArcCatalog or using the Create Raster Catalog tool. You can then load one or more raster datasets into your empty raster catalog. ![]() When you create a raster catalog in a geodatabase, you are creating an empty location to contain multiple raster datasets. Creating raster catalogs in a geodatabase ![]()
