Kibana 4.5.4 tile map visualization

How do I configure Kibana to use the TileMap?

I am using Kibana 4.5.4

My logstash config file is as follows

geoip {
source => "clientip"
target => "geoip"
database => "/etc/logstash/GeoLiteCity.dat"
add_field => [ "[geoip][coordinates]", "%{[geoip][longitude]}" ]
add_field => [ "[geoip][coordinates]", "%{[geoip][latitude]}" ]
}
mutate {
convert => [ "[geoip][coordinates]", "float"]
}

However, In the kibana tile map it says:

No Compatible Fields: The "iot_logs" index pattern does not contain any of the following field types: geo_point

Is there a different way I am suppose to configure the tile map?

I followed this tutorial

This is more of a Logstash question, but I'm guessing the filter you have right now just giving you some float fields, but nothing that's mapped with geo_point type, which is needed for Kibana TileMap visualization.

It would help if you could share the mapping you currently have. What is the output if you do: curl -XGET localhost:9200/iot_logs/_mapping ?
