Here is the code for Js File: 

import {LightningElement ,api,wire} from 'lwc';
import { getRecord, getFieldValue } from 'lightning/uiRecordApi';
const NAME = 'Pokemon__c.Name';
const LATITUDE = 'Pokemon__c.Location__Latitude__s';
const LONGITUDE = 'Pokemon__c.Location__Longitude__s';


const pokemonField = [NEME,LATITUDE,LONGITUDE];
export default class PokemonLocation extends LightningElement {
@api recordId;
mapMarkers= [];
name;
cardTitle;
@wire (getRecord, {recordId: '$recordId', fields :pokemonField})
getPokemons({ error, data}) {
if(error) {
console.error('erro: '+JSON.stringify (error))
}else if(data){
this.name = getFieldValue(data, NAME);
this.cardTitle = this.name;
const Latitude = getFieldValue(data, LATITUDE);
const Longitude = getFieldValue(data, LONGITUDE);
this.mapMarkers = [ {
location: {Latitude, Longitude},
title : thin.name,
description: 'Coords : ${Latitude}, ${Longitude}'
}]
console.log("this.mapMakers:"+JSON.stringify(this.mapMakers))
}
}
}

HTML :

<template>
    <lightning-card title={cardTitle} icon-name="standard:address">
       <lightning-map map-markers={mapMakers} zoom-level="12">
       </lightning-map>
    </lightning-card>
   
</template>
