v28 v29 49 49 50 50 * (2/week) Map Thousands of Points - Within a few days we are likely to have a thousand of assessment points. I'm not sure if the current map renderer is capable of scaling to rendering thousands of points in a browser (I know this has been an issue with some mapping libraries in the past). One approach I've seen in the past is to use a Flash map viewer that can happily scale to render thousands of points. We will probably get to a thousand assessments in 2-3 days (we start in about 12 hours time) and it is very important that we can scale to efficiently render thousands of points. 51 * Shouldn't be an issue as we have the Cluster Strategy enabled (FPB) 51 * The map-panning performance shouldn't be an issue as we have the Cluster Strategy enabled (FPB) 52 * However we need to move away from the current model of writing the Features into the webpage as this will make the initial map download too large. I have already started work on replacing this with a dynamic download of features using GeoJSON which can make use of the BBOX Strategy to minimise downloads...I will progress this. (FPB) 52 53 53 54 * (2/days) Print Assessment Forms - It would be good to be able to generate forms from the application. Ideally, it would be possible to have addresses (and if we had them prupi's/gisratingid's) preprinted on forms. This would be nice to have, but is lower priority that a number of the above capabilities. For a bonus gold star, being able to draw a polygon, and have forms printed out for all entries in the polygon would be wickedly useful. We often assign assessments by block. 54 * Status: Form is printable in a near OCR-compliant way, although currently these forms won't be OCRable (fix by Monday? Fix will only work with new forms, not ones printed today) 55 55 * Status: Form is printable in a near OCR-compliant way, although currently these forms won't be OCRable (fix by Monday? Fix will only work with new forms, not ones printed today) 56 * To be able to pre-print forms, we'd need a dump of that database available to load. If we get this database then we can take a look at being able to do this. Map-based selection of records is on the roadmap, but is unlikely to get done within the timeframe for this response, I'm afraid. (FPB) 56 57 == Considerations == 57 58 * System may need to scale to potentially handle 100k assessment records after 1 month.
