The Environmental Portuguese Agency (APA) has recently joined the international community of highly satisfied users of Spatineo Monitor. APA hosts over 150 spatial web services, 40% of them being INSPIRE services. It is then crucial that APA keeps most of their services at high availability levels. Hence, having a reliable tool using a consistent and representative methodology for measuring and monitoring the availability of the services is essential to APA’s business. Also, by better knowing the level of usage using an integrated system like Spatineo Monitor, APA can effectively optimize the investments in the Spatial Data Infrastructure in a way that would neither be feasible nor practical by using several scattered tools.
