Colombia with great potential SOTA

Aquí hay algunos recursos que encontré:
Fuentes clave de datos cartográficos para Colombia

1. Instituto Geográfico Agustín Codazzi (IGAC) – Instituto Cartográfico Nacional de Colombia

El IGAC es el organismo oficial del gobierno encargado de producir datos cartográficos y geográficos en Colombia, incluyendo mapas topográficos e infraestructura SIG. Publica datos a través de su portal SIGOT y del atlas digital “Colombia en Mapas” (CeM), que ofrece capas SIG accesibles e imágenes satelitales para descarga y análisis.

Estos recursos pueden usarse para obtener mapas base precisos y datos de elevación a varias escalas (1:25.000, 1:100.000) que pueden apoyar la identificación de cumbres y el análisis de prominencia.

2. Servicio Regional de Procesamiento Topográfico GeoSUR

GeoSUR es una iniciativa latinoamericana que ofrece Modelos Digitales de Elevación (MDE) gratuitos con resoluciones de hasta 30 m, junto con derivados del terreno (por ejemplo, pendiente, relieve sombreado, cuenca visual), todo a través de una interfaz web.

Es especialmente útil para generar curvas de nivel y perfiles de elevación en amplias zonas andinas.

3. Fuentes globales de MDE: SRTM y Viewfinder Panoramas

La Misión Topográfica por Radar Shuttle (SRTM) proporciona datos de elevación global gratuitos (en formatos .hgt o GeoTIFF), adecuados para modelado general de elevaciones.

Viewfinder Panoramas ofrece mosaicos MDE descargables de 3 segundos de arco derivados de datos SRTM.

Estos se pueden usar para realizar verificaciones iniciales de elevación e identificar relaciones potenciales entre cumbre y collado.

4. Plataforma OpenTopography

OpenTopography alberga conjuntos de datos globales en cuadrículas de alta resolución que pueden utilizarse para análisis del terreno y detección de cumbres.

Adecuado para modelado detallado de elevaciones si se requiere mayor detalle para la detección de cumbres prominentes.

5. OpenStreetMap (OSM)

OSM es un proyecto de cartografía colaborativa que recopila información geográfica a nivel de terreno, aunque la cobertura varía por región. Puede ayudar a identificar picos con nombre o senderos, y enriquecer los datos con contexto local.

Herramientas como mapatones y aplicaciones móviles de mapeo pueden ayudar a mejorar la cobertura de manera colaborativa en áreas andinas específicas.

6. MapBiomas Colombia

Ofrece mapas de referencia de cobertura y uso del suelo (por ejemplo, glaciares, cobertura forestal) con alta resolución espacial, lo cual puede ayudar a validar características geográficas relacionadas con cumbres (por ejemplo, identificar páramos o la extensión de glaciares).

Hey gracias Colegas por los aportes, lamentablemente los mapas que tienen en la Augustin Codazzi no aplican para los administradores de SOTA, ya viaje a Bogota directamente a la oficina de la augustin y tambien le escribimos a ellos y lo que noes enviaron no sirvem los puntos estan en cartografia y tenemos las coordenadas y elevacion pero tampoco sirve a SOTA, asi que seguiremos intentando hasta que podamos posicionar nuestro Pais en SOTA. atentos. Gracias…

Alex, por ahí pueda sonar disparatado mi comentario pero alguna institución militar que trabaje conjuntamente con la comunidad civil? Te comento esto porque todo el relevamiento cartográfico de Argentina era realizado por el ¨Instituto Geográfico Militar¨ (Actualmente Instituto Geográfico Nacional) La entidad madre de los radioaficionados en Colombia no podría darte una mano en esto?
Realmente es una pena que con el potencial que hay para SOTA no puedan hacerlo.
Suerte!

[HK4SSI]

Gracias Takeo, desafortunadamente la entidad encargada no tiene los mapas que exige SOTA, El Alma Mater de la Radioafición en el Pais no hace mucha precensia y estamos buscando por todas las instancias poder suplir las necesidades exigidas por SOTA. por eso pedimos un poco de flexibilidad, queremos participar pero no esta especifico lo que ellos requieren. Seguimos trabajando…

What kind of volunteer help is most useful here. How can we as a community help to get new associations online? Can we generate a list of peaks that need to be verified?

Could we consider admitting a new association in this situation with something like a P200 criteria that could be determined with the existing, limited data sources? As a more restrictive criterion this would at least ensure no peaks under P150 were included and would allow for updating summit lists later as better data becomes available.

As a new SOTA member I don’t want to re-litigate what are likely old arguments, but I would love to find ways to optimize inclusion without having to compromise on the integrity of an association.

Tony, we are grateful for any help, but it is not something to be discussed here, there is a channel on the website to directly contact the MT and the summit team. The summit team works often for months to bring a new Association into being, and likely don’t pay much attention to this reflector.

Perhaps and perhaps not. Besides identifying the summit itself as the highest point amongst possibly several alternative choices, we need to identify the highest col that leads to a higher summit, which may well be many miles away. Since col heights are subject to the same possible errors you see that there is a possibility of the errors adding. Bear in mind also that there are at any time several Associations being actually worked on, and as the easier (well-mapped) Associations are completed the difficult ones come to the top of the pile and take more time.

Anyway, just as this is not the place to discuss these matters, I am not the best person to talk about the problems - my main responsibility is moderating this reflector. WE have an expert team who over the last couple of decades have brought 215 Associations on line, and who besides working on new Associations are also updating the current Associations as new data becomes available - the work never ends! If you think you can help then use the contact page on the Home website and talk to an expert.

Thanks for taking the time for a detailed reply, and very interesting to hear about the subtitles and pain of the process

Good afternoon, I totally agree that there is a team to assess the issues, but in the absence of a solution from the MT and we, we decided to scale it up to the forums for help from the other participants in the program and look for a solution that benefits us all. We continue to receive suggestions and we would like to find ways to add Colombia to the SOTA program. Thank you…

This is what we all would like.

@KM6AM

something like a P200

Please have a read of the post I linked above to understand why the prominence boundary chosen isn’t really the issue. It’s not as simple as it looks on the surface because prominence brings in second order effects.

The primary issue always is mapping. It needs to be at least 1:50k, with 10m contours. It can’t be based on SRTM because we know how wrong that can be, which rules out all the OpenXXXXXMaps variants, ArcGIS, etc. That basically leaves government mapping which is sometimes unavailable or expensive. It’s typically inaccessible to non citizens in countries with more hostile neighbours or a history of conflict.

The other issue is that back when we had poor or less diligent mapping processes that let through some bad summits and took more effort to fix, we got slammed for having not having a strict process and when we put in processes to ensure that doesn’t happen we get slammed for being too inflexible. So who’d volunteer for something in the ham radio space where you can’t win?

So true.
