{"Image DocumentName": "What is the ADDE?Client/server data access model developed for McIDAS, but not limited to serving McIDAS data.", "Image ImageDescription": "In use for nearly 10 years. 4 primary types of data objects. GRID, IMAGE, POINT, TEXT. Primary servers handle McIDAS format files (AREA, GRID, MD, LW) Secondary servers read non-McIDAS formats (GINI, NEXRAD Level III, MODIS, netCDF,\u2026) Allows browsing and subsetting of datasets. ADDE was originally developed as part of the McIDAS display and analysis package. It is based on a client/server data access model and allows McIDAS users to access data on local and remote servers. There are 4 basic types of data that ADDE defines \u2013 grid (gridded data), image (image data), point (observational data) and text (text bulletins). The design of ADDE is such that you could serve up a grid as an image, or an image as a grid. While the core servers distributed with McIDAS understand McIDAS-formatted files, the API allows the development of subservers to handle non-McIDAS data formats. These subservers adapt the data to the appropriate ADDE data structure which is then passed on to the client. Another important feature of ADDE is its browse and subset capabilities. You can probe a dataset to determine what its temporal and spatial characteristics as well as what parameters are available. And, you can subset the data before returning it to the client so if you had a 1km global Vis image, and you were only interested in a view over Albuquerque, you can pull out just that piece you are interested in.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
