With the advent of wireless sensor nodes, we can create a system of environment monitoring in urban areas. Although variable sensors can be deployed densely in certain area, it is not cost effective to use sensors more than necessary. Instead of embedded sensors, we can utilize information emitted from walking people. Although the technique of localization is advanced, there still exists a location error. It brings a huge impact for mapping the data, especially in large scale. Based on the idea, we propose a system of extracting environmental information with considering degree of location error. In our system, we have extended WINFO+, previously developed system for broadcast personal sensed information, to overcome issues about a location error.
