DESCRIPTION:MAPi is a web platform for online mapping conceived as a public
  participation tool for schools and organized civil society. Its main func
 tionalities of visualization\, analysis\, and collection of spatial data w
 ere developed to encourage participatory urban planning\, especially focus
 ing students and teachers from basic education.\nThe Center for Metropolit
 an Studies (CEM)\, which is the research center that hosts MAPi´s project
 \, has been responsible for producing and openly sharing databases (cartog
 raphic and non-cartographic) since its inception 20 years ago.  More recen
 tly\, CEM expanded its activities in this technology transfer area to deve
 lop interactive web systems\, like ReSolution and Schools portals\, built 
 from the interaction with the center's academic research work and agendas.
  So the idea is to bridge the gap between highly complex research and tech
 nology transfer to academic and non-academic society\, respecting the prin
 ciple of open data and software. All data produced and all softwares devel
 oped\, including its source codes\, are available at no cost.\nIn this con
 text\, however\, there is a great challenge to make the knowledge produced
  by the CEM\, especially the cartographic databases\, continuously accessi
 ble to a portion of society that does not master geospatial analysis techn
 iques. Although the ecosystem that provides tools for this type of analysi
 s is increasingly more accessible\, including through the web\, they are s
 till far from being widely adopted in non-specialized contexts\, such as c
 lassrooms.\nTo tackle this challenge\, MAPi arises to perform as a tool th
 at can expand the use of spatial data in primary and secondary schools. So
  it has the twofold challenge of gathering simplicity in its navigation to
  ensure a friendly experience with complexity of technique specificities o
 f exploring and visualizing spatial data\,  especially for the non-special
 ized public.\nThus\, MAPi has\, since its first version\, native integrati
 on with CEM's spatial data repository\, GeoCEM\, which is developed based 
 on the GeoNode software\, with its metadata stored on Geoserver..\nThrough
  Geonode\, MAPi queries the layers that are published on GeoServer using t
 he Web Feature Service (WFS). WFS specifies an interface for accessing and
  manipulating geographic elements using the HTTP protocol. The advantage a
 nd reason for choosing this standard is its ability to extract only the de
 sired data at the element and attribute level. In this way\, we can build 
 a dynamic platform that creates thematic maps in real-time from the parame
 ters chosen by the user\, characterizing it as an interactive mapping plat
 form.\nMAPi presents as its main tool for spatial data analysis the interf
 ace for creating choropleth thematic maps. This type of map is used in MAP
 i to represent data collected from geographic units such as census tracts 
 and districts. For this functionality\, the platform allows the choice bet
 ween some color palettes (sequential\, divergent\, or qualitative)\, which
  are associated with the polygons of the geographic units according to the
  class division (quantile or natural breaks). The selection of multiple sp
 atial data layers that are added as a Vector Tile layer in OpenLayers\, ma
 kes it possible for the user to analyze and compare different themes or pe
 riods simultaneously. To serve non-specialized audiences\, we maintain onl
 y the most essential tools of thematic mapping so that users can in a few 
 steps build visualizations capable of extracting analyses\, maintaining so
 me level of parameterization to adapt to the type of phenomenon. Thus\, th
 rough the OpenLayers and WFS resources\, we make parameterizable for each 
 layer its visibility\, the attribute that will be associated with the fill
  color\, the data classification method\, the color palette\, and the attr
 ibutes that will be displayed in the dynamic map legend (based on attribut
 e values).\nFinally\, the third axis of functionality\, collaborative mapp
 ing\, aims to provide\, in a simplified way\, tools for the production of 
 spatial data. We understand here that this functionality can be a tool tha
 t enables the expansion and updating of data coverage that official agenci
 es are unable to perform. In this way\, we intend to create an area within
  the platform that allows the creation of forms with location fields to cr
 eate spatial data to be viewed and analyzed together with the other data o
 n the platform. Currently\, only the integration with Mapillary partially 
 accomplishes this goal through the consumption of the visualization of the
  cover layer\, and visualization of the photo sequences available in Mapil
 lary by its users.\nOne potential application in education from collaborat
 ive mapping functionalities is the support in the discussion about neighbo
 rhood plans\, that are  instruments foreseen under master plan development
 \, like the example from the megacity of São Paulo. The tool is under tes
 t with basic education teachers that want to promote mapping activities wi
 th MAPi in urban geography classes\, and also within mathematics classes w
 here they can address methodological issues of the results of this mapping
  to support basic concepts related to statistics in the classroom. Our nex
 t challenges are the optimization of performance for large volumes of data
  and the implementation of more complex collaborative mapping functionalit
 ies in a Agile methodology\, with constant interaction with teachers that 
 envision MAPi´s potential to foster engagement of students in urban plann
 ing.
