4ª ATIVIDADE: A aprendizagem através de ferramenta digital eletrônica para a construção de conceitos cartográficos
Autor: Marcus e Miguel Angelo | Publicado: 2011-05-18T20:54:00-03:00

Google Earth
O Google earth é uma importantíssima ferramenta deacesso gratuito para os usuários da web. Ela permite diversas possibilidades, inclusive inserida nas praticas pedagógicas, auxiliando ao aluno no entendimento da leitura cartográfica do mundo, promovendo o aprendizado de maneira dinâmica, interativa.
Marcadores, caminhos e coordenadas 
Utilizando marcadores, registramos os locais no mapa, determinados pontos onde nos interessam desenvolver algum trabalho.


Figura 1 - marcadores, caminhos e coordenadas


Os caminhos colocados em vermelho na Figura 1 estabelecem traçados nos mapas delimitando distancias e possíveis percursos, até levantamento de dados altimétricos, percorrer o percurso do recorte e principalmente a distancia em diversas escalas: KM, M, Jardas, Pés, Milhas (Náuticas), Smoots, Polegadas e etc. Em Lugares-&gt; propriedades pode-se fazer conversões dessas medidas e estabelecer descrições.
Caminho 1: Distancia: UFS -&gt; Oceanário. 9,0 KmCaminho 2: Oceanário –&gt; Shopping Riomar. 3,68 KmCaminho 3: Shopping Riomar -&gt; Jardins. 1,32 KmCaminho 4: Shopping Jardins -&gt; Estádio Lourival Batista. 2,1 KmCaminho 5: Estádio Lourival Batista. -&gt; Praça Olímpio Campos 1,54 KmCaminho 6: Praça Olímpio Campos. -&gt; Ponte Aracaju-Barra 2,15 KmCaminho 7: Ponte Aracaju-Barra. -&gt; Bugio 5,63 Km Caminho 8: Bugio -&gt; Restaurante “O Sapatão”. 5,16 KmCaminho 9: O Sapatão. -&gt; UFS
Coordenadas, Pontos cardeais, Altitude e data da imagem.


Figura 2 - estádio de futebol "Batistão"

As imagens grifadas em vermelho (Figura 1) identificam as informações da data, coordenadas e altitude de visualização. Mais acima, está o circulo representando os pontos cardeais com a letra “N”, sendo que ao girar com o cursor, a imagem visualizada acompanhará a direção desejada. 
Escala
Utilizando os recursos de altitude através do zoom das imagens, pode-se trabalhar em diversas escalas espaciais desde, o local até o global. Em camadas, possibilita-se selecionar as informações desejadas e necessárias na consulta de acordo com o interesse como: Limites dos territórios, fotos, pontos turísticos, climas, estradas e lugares.

Resgate histórico das imagens:
Podemos analisar também através das imagens de satélite do Google Earth a produção do Espaço, observando a topografia em anos seqüenciados, percebendo a modificação da natureza via trabalho. Buscamos três imagens ordenadas da Orla de Atalaia de Aracaju para exemplificar isto:&nbsp;


Altitude do ponto de visão 1,29 Km.
