       This work describes ongoing research which aims to evaluate the
       limitations of existing tools to support geographic information
       retrieval  on  the Web. More specifically, we are interested in
       assessing  how  well queries involving geographic relationships
       can  be  specified  and  executed using existing Web tools. Our
       evaluation considered three different aspects: the relevance of
       the  results and the time and complexity of the steps necessary
       to  obtain  these results. More than thirty Web users performed
       five  tasks,  considering  five  scenarios.  Experiment results
       demonstrate  that  existing Web tools are not enough integrated
       to meet user needs regarding the specification and execution of
       queries involving spatial relationships.
