      Quando usas GeoExt tens mesmo que utilizar mais duas bibliotecas
      javascript: o OpenLayers e o ExtJS. Basicamente o GeoExt &eacute; uma
      biblioteca que faz a "liga&ccedil;&atilde;o" entre os componentes do OpenLayers
      e os componentes do ExtJS. <br>
      <br>
      O openlayers &eacute; portanto utilizado para a componente espacial, o
      extjs &eacute; utilizado para a interface gr&aacute;fica e maipula&ccedil;&atilde;o de dados
      alfanum&eacute;ricos e finalmente o GeoExt &eacute; utilzado porque cont&eacute;m j&aacute;
      elementos espec&iacute;ficos que misturam os anteriores (por exemplo:
      painel de maps, painel de legenda, combobox de escalas, stores de
      dados desenhados especificamente para pedidos WFS e
      WMSgetCapabilities, componentes de impress&atilde;o, etc...).<br>
      <br>
      Depois podes enventualmente ter que utilizar a biblioteca Proj4Js
      que possibilita a defini&ccedil;&atilde;o de sistemas de referencia&ccedil;&atilde;o espacial
      (definidos &agrave; la Proj) e convers&otilde;es entre sistemas utilizando os
