HSLayers

● JavaScript library for creation of rich web-based geo-applications (Geoportals)

● Based on two components● OpenLayers http://openlayers.org (2.10)● ExtJS http://sencha.com (3.x)

● GNU/GPL● Designed for building MapViewer component of

INSPIRE infrastructure

INSPIRE

● Infrastructure for spatial information in Europe● Member States shall establish a network of

services for the spatial data sets:● Discovery service● View service● Download service● Transform service● Invoke service





Server Side vs Client Side

Other Components

● Query (WMS GetFeatureInfo, support for text, html, gml, various ESRI formats, …)

● Projection switcher● Editing of vector data (attributes, geometry | point,

line, polygons)● Other components, desigend to fit into regional

Geodata Infrastructure● Quering of Parcels ● Links to particular Municipality from Map directly

● Integration with Metadata Catalogue





Under construction

● Time support● Closer integration with SLD● WCS, WFS (nearly done)● WFS Filtering● ExtJS 4.0 support● ….





Conclusion

● HSLayers is tool designed for easy clients creation, used (not only) within INSPIRE infrastructure.

● It is mature project, used in several europan projects (Plan4all, Habitats, …) and on czech national INSPIRE Geoportal
