This section provides information relating to the File (toolbar) feature used with the Visual Data Analytics Web GIS (VDAW4). The purpose of these features is to move a layer from one project to a different project, saving the new project for use by yourself or others. Click the File feature on the toolbar to view these features. These features are not available at this time using VDAW3 or iVDA. This document is written for a Windows computer, but the general steps also work for Mac computers. Available Features via the File Toolbar • Userfile download • Userfile upload • Save Project • Open Project This document is written for users generally otherwise familiar with VDAGIS tools and operations. An Example/Application Consider the application of copying .. the median age by county layer (County 2024 Median Age) layer .. from the VDA GIS project "Population County -- Age/Gender" .. to the VDA GIS project "American Community Survey 2023 County Data Profiles". Complete the following steps using VDAW4. You will be able to display median age by county (a label) and median age by county (a label) from the ACS 2023 county file (item D018). Userfile download First, select the project where the layer is located. e.g., Population County -- Age/Gender With a project open, select a layer making it the active lauer (left click name) Click the Userfile download. A form appears. Click the Make Shapefile. The name of the shapefile is shown; it will not be familiar and is assigned by the system. Click the Download button; the downloaded file will be in a folder on your computer. The shapefile correponding to that layer has been downloaded. Close the Userfile download frame. Userfile upload First, select the project where the layer is to be added e.g. American Community Survey 2023 County Data Profiles. Click the Userfile upload. A form appears. Click the Choose file. The name of the shapefile is shown; assigned by the system. Select the shapefile to be added. This name is a ZIP file and was stored on your computer. A new layer is added at the top of the Legend Panel corresponding to the shapefile. Close the Userfile upload form. The map window shows the shapefile as the top layer. It has a gray fill pattern. Optionally modify the layer attributes with the Tools>Layer Editor. Add a label (medage as upper, center) Optionally move the new layer down with the up/down feature. Save Project Click the Save button to save the project e.g. while American Community Survey 2023 County Data Profiles with new layer is opened. The original project will not be affected. Open Project Any authorized user can now open the new project. The new project name is not promoted or listed. To Open the project with the added layer, click Opem Project. a form opens showing the projects saved using this method. the most recent project saved is shown at top. Displaying and interpreting the differences in ages. Why is there a difference in the two median ages diaplayed? 1) the ACS 2023 data are 5-year estimates based on a survey (the latest) -- centric to 2021 2) the data from the 2024 median age by county are two years more recent and based on model-based estimates. ACS 2023 data are 5-year estimates based on a survey (the latest) -- centric to 2021 .. zoom in to Kansas counties .. click graphic for larger view  .. Sedgwick County (Wichita) .. median age 35.9 years (statistical survey with MOE known) 2024 median age by county are two years more recent and based on model-based estimates .. click graphic for larger view  .. zoom in to Kansas counties .. Sedgwick County (Wichita) .. median age 36.4 years (model-based, no MOE available) Role of GIS for Demographic Economic Analysis A Geographic Information System (GIS) is a computer -based tool that allows users to store, analyze, visualize, and interpret geographic data. Geographic data, also known as spatial or geospatial data, identifies the location of features on earth. GIS combines the visual elements of maps with the ability to link characteristics about those features in datasets. This relationship allows GIS to locate, display, analyze, and model data. GIS technology integrates geographic data with statistical and administrative data using statistical methods and analytics. These abilities make GIS valuable to a wide range of public and private enterprises for explaining events, predicting outcomes and planning strategies. And collaborating on those issues. Terms of Use .. goto top There is no warranty regarding any aspect of this using this project. The user is solely responsible for any use made of tools and data contained in project files. About iVDA & VDAGIS .. goto top iVDA is an HTML iframe embedded version of VDA Web GIS. VDAGIS tools and data have been developed and are updated/supported by Warren Glimpse/ProximityOne/Alexandria, VA USA and Takashi Hamilton/Tsukasa/Osaka, Japan. Support Using these Resources .. goto top Learn more about accessing and using demographic-economic data and related analytical tools. Join us in a Data Analytics Lab session. There is no fee for these one-hour Web sessions. Each informal session is focused on a specific topic. The open structure also provides for Q&A and discussion of application issues of interest to participants. Additional Information ProximityOne develops geodemographic-economic data and analytical tools and helps organizations knit together and use diverse data in a decision-making and analytical framework. We develop custom demographic/economic estimates and projections, develop geographic and geocoded address files, and assist with impact and geospatial analyses. Wide-ranging organizations use our tools (software, data, methodologies) to analyze their own data integrated with other data. Contact us (888-364-7656) with questions about data covered in this section or to discuss custom estimates, projections or analyses for your areas of interest. |
